unix: 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. This change only affects Linux versions prior to 5.8. Linux 5.8 added the faccessat2 system call, which we use in preference to the internal implementation. No test since we cannot easily change file permissions when not running as root and the test is meaningless if running as root.
