SOLARIS: Correct misplaced osi_machdep.h #endif

SOLARIS: Correct misplaced osi_machdep.h #endif

Commit 64778fd7bece52360482f9a51f19b34dac1d2678 removed some '#ifdef
KERNEL' blocks, but for one block in SOLARIS/osi_machdep.h, the wrong
trailing #endif was removed. This effectively makes the last part of
the file Solaris 10+ only, and bypasses the header guard. On systems
before Solaris 10, this causes us to lose the osi_procname definition,
which eventually shows up as an undefined symbol.

So, reinstate the original #endif, and remove the correct #endif
instead.
