[ELF][MIPS] Fix primary GOT sometimes overflowing by one or two words
If we fail to merge a secondary GOT with the primary GOT but so far only
one merged GOT has been created (the primary one), the final element in
MergedGots is the primary GOT. Thus we should not try to merge with this
final element passing IsPrimary=false, since this will ignore the fact
that the destination GOT does in fact need a header, and those extra two
entries can be enough to allow the merge to incorrectly occur. Instead
we should check for this case before attempting the second merge.
Patch by James Clarke.
