build: Fix kernel oplock test
In a pure docker environment with overlayfs F_GETLEASE works on /tmp,
but F_SETLEASE does not. This test now correctly detects that.
The effect is that the samba-fileserver environment would run fine in
a shared gitlab runner, at the price of not testing kernel oplocks. We
could move the kernel oplock tests to another environment that for
other reasons can't run on shared gitlab runners.
