pkg/signal: ignore SIGURG on all platforms
Other Unix platforms (e.g. Darwin) are also affected by the Go
runtime sending SIGURG.

This patch changes how we match the signal by just looking for the
"URG" name, which should handle any platform that has this signal
defined in the SignalMap.

pkg/signal.CatchAll: ignore SIGURG on Linux
Do not handle SIGURG on Linux, as in go1.14+, the go runtime issues
SIGURG as an interrupt to support preemptable system calls on Linux.

This issue was caught in TestCatchAll, which could fail when updating to Go 1.14 or above;

When "ParseSignal" function parse sigStr from SignalMap, it find the signal object with key ("SIG"+sigStr). But  EMT signal named "SIGEMT" in SignalMap structrue, so the real key is "SIGSIGEMT" , and cannot find the target signal.

86f080cff0 Use Mkdev, Major and Minor functions from golang.org/x/sys/unix
Update golang.org/x/sys to 8dbc5d05d6edcc104950cc299a1ce6641235bc86 in
order to get the Major, Minor and Mkdev functions for every unix-like
OS. Use them instead of the locally defined versions which currently use
the Linux specific device major/minor encoding.

This means that the device number should now be properly encoded on e.g.
Darwin, FreeBSD or Solaris.

Also, the SIGUNUSED constant was removed from golang.org/x/sys/unix in
https://go-review.googlesource.com/61771 as it is also removed from the
respective glibc headers.

Remove it from signal.SignalMap as well after the golang.org/x/sys
re-vendoring.

55a367d2fe Ignore SIGPIPE events, resolves #19728
Using golang 1.6, is it now possible to ignore SIGPIPE events on
stdout/stderr.  Previous versions of the golang library cached 10
events and then killed the process receiving the events.

systemd-journald sends SIGPIPE events when jounald is restarted and
the target of the unit file writes to stdout/stderr. Docker logs to stdout/stderr.

This patch silently ignores all SIGPIPE events.

e787296c75 Ensure goroutines dump is not truncated
Calling runtime.Stack requires the buffer to be big enough to fit the
goroutines dump. If it's not big enough the dump will be truncated and
the value returned will be the same size as the buffer.

The code was changed to handle this situation and try again with a
bigger buffer. Each time the dump doesn't fit in the buffer its size is
doubled.
