mk/tools: Switch to pwd builtin on SunOS.

pkgsrc switched to using /bin/pwd back in 2003 due to some undocumented errors
in buildlink2, but I don't see any failures with this in bulk builds and it
avoids a large number of unnecessary execs.  Limited to SunOS for now as that's
all I've tested, but other platforms are more than welcome to follow suit.
