[PATCH 3/5] rpmvercmp: Return -1/0/1 as function says it will

[Dan Nicholson]

strcmp is only guaranteed to return !0 when the strings are unmatched
while rpmvercmp says it will return only -1 or 1 in those cases.

pkg-config currently only checks for !0, so this doesn't actually fix
any issues here. However, this is harmless and helps minimize the diff
with upstream rpmvercmp.
