setting an explicit groupId to /usr/bin/dotlockfile breaks fedora coreos tests

[LakshmiRavichandran1]

Hi, is setting an explicit groupId intended here https://github.com/miquels/liblockfile/blob/master/Makefile.in#L80-L84 ?
It is breaking one of our test case in Fedora Coreos/rawhide for s390x.

--- FAIL: fcos.filesystem (27.34s)
15:40:05  
15:40:05      --- PASS: fcos.filesystem/suid (0.35s)
15:40:05  
15:40:05      --- FAIL: fcos.filesystem/sgid (0.24s)
15:40:05  
15:40:05              files.go:69: Unknown SUID or SGID files found: [/usr/bin/dotlockfile]

we realised that the updated s390utils in Fedora Coreos/rawhide has as a new dependency - the liblockfile package which owns the file with the groupId set.
