Solaris: setpag should verify that ngroups will not overflow

Our ngroups management (since PAGs are still encoded as 2 groups) needs
to ensure that we do not overflow what we are prepared to handle,
and do not panic due to misheld mutexes if we have to return an error
when handling it.

FIXES 131878 (CVE-2015-3286)

(cherry-picked from commit 8ce4a3905268385d3f5a0e11f20594875467cae6)
