[release-branch.go1.17] syscall: check correct group in Faccessat
The Faccessat call checks the user, group, or other permission bits of a
file to see if the calling process can access it. The test to see if the
group permissions should be used was made with the wrong group id, using
the process's group id rather than the file's group id. Fix this to use
the correct group id.
No test since we cannot easily change file permissions when not running
as root and the test is meaningless if running as root.
For #52313
Fixes #52439
