os/user: implement (*User).GroupIds on solaris

Browse Source 
It seems like getgrouplist is supported since Solaris 11.3 (released in
2016):
https://docs.oracle.com/cd/E86824_01/html/E54766/getgrouplist-3c.html

Use it to implement (*User).GroupIds on solaris, like on other Unix
platforms.

Unfortunately it looks like getgrouplist was added to illumos only
fairly recently, see
f2c438c505

Thus, don't use it on GOOS=illumos for now.

Updates #14709
