32ab09a930 LibCore: Add a wrapper for execvpe() and friends 
This is a single function, which behaves like the various LibC exec()
functions depending on the passed parameters. No direct equivalent is
made for execl() - you have to wrap your arguments in a Span of some
kind.

On Serenity, this calls the syscall directly, whereas Lagom forwards to
the appropriate LibC function.

ceba27c3fe LibCore: Add openat() syscall wrapper and improve open's implementation 
We don't need va_args in open(), we can just use a default parameter.

6eebd69b70 LibCore: Add Core::System::drop_privileges() 
In a few places we intentionally drop privileges to reduce the potential
security surface area of networked program, with the pattern of:

```
if (setgid(getgid()) || setuid(getuid()) {
    return 1;
}
```

We can make this a bit nicer to use by creating a wrapper.

ddf9987c39 LibCore+LibC: Add wrapper for setenv 
I also added a common interface with StringView compatible parameters:

int serenity_setenv(const char*, ssize_t, const char*, ssize_t, int)

This function is called by both C and C++ API for setenv().

cf1f58d51c LibCore/System: Add anon_create syscall wrapper 
This wrapper is particularly helpful as we use a combination of similar
syscalls on Linux to simulate the behavior of the Serenity-exclusive
anon_create syscall. Users therefore won't have to worry about the
platform anymore :^)

1e4117f1e1 LibCore: Add syscall wrapper for getgroups() 
This wrapper does all the grunt work of figuring out how many extra GIDs
there are, and then returning them nicely wrapped in a Vector<gid_t>.

63760603f3 Kernel+LibC+LibCore: Add lchown and fchownat functions 
This modifies sys$chown to allow specifying whether or not to follow
symlinks and in which directory.

This was then used to implement lchown and fchownat in LibC and LibCore.

7772309169 LibCore+chown: Return ErrorOr<Optional<...>> for getgrnam and getpwnam 
This patch returns an empty Optional<...> instead of an Error for
Core::System::getgrname and Core::System::getpwnam if we can't find a
matching group or user entry.

It also updates the 'chown' utility to support this new behavior.

289cf8d7ef LibCore: Add ErrorOr wrappers to socket syscalls 
These are all pretty simple so I thought I would add them all in one go:

- socket()
- bind()
- listen()
- accept()
- accept4()
- connect()
- shutdown()
- send()
- sendmsg()
- sendto()
- recv()
- recvmsg()
- recvfrom()
- getsockopt()
- setsockopt()
- getsockname()
- getpeername()
- socketpair()
