Linus Groh 51bcfb5a44 Meta: Update lint-{clang-format,shell-scripts}.sh to take a list of files
This should speed up pre-commit a bit as only files that are staged will
be processed, and clang-format and shellcheck are only invoked once, not
for every file. When no arguments are given (e.g. on CI), it still uses
'git ls-files'.
