Add system call: listxattr family

In newer coreutils versions, ls -l may call listxattr() which we do not handle at this time. Therefore, ls -l prints:

❯ LD_PRELOAD=/home/evie/remote_mac/gekkofs/cmake-build-debug/src/client/libgkfs_intercept.so ls -l /tmp/gkfs_mountdir/blubb
ls: /tmp/gkfs_mountdir/blubb: No such file or directory
ls: /tmp/gkfs_mountdir/blubb/bashrc: No such file or directory
ls: /tmp/gkfs_mountdir/blubb/bashrc2: No such file or directory
ls: /tmp/gkfs_mountdir/blubb/bashrc23: No such file or directory
ls: /tmp/gkfs_mountdir/blubb/bashrc234: No such file or directory
ls: /tmp/gkfs_mountdir/blubb/bashrc2345: No such file or directory
ls: /tmp/gkfs_mountdir/blubb/bla: No such file or directory

drwxrwxrwx 1 evie evie    0 Jan  1  1970 bla

strace reads:

listxattr("/tmp/gkfs_mountdir/blubb/bashrc2345", 0x7ffe4aad88c0, 152) = -1 ENOENT (No such file or directory)
write(2, "ls: ", 4ls: )                     = 4
write(2, "/tmp/gkfs_mountdir/blubb/bashrc2"..., 35/tmp/gkfs_mountdir/blubb/bashrc2345) = 35
write(2, ": No such file or directory", 27: No such file or directory) = 27
write(2, "\n", 1
)

All system calls from the listxattr family (man 2 listxattr) should therefore be intercepted by GekkoFS but marked as not supported with the corresponding error code. See getxattr() hook.
