Delete unused misc/getpw.c from libc.

@hexcoder- reported in https://github.com/davidgiven/ack/issues/57
that our getpw() has bugs.

I don't fix these bugs, because Illumos and Linux manual pages say
that getpw() is obsolete.  The function can overflow its buffer, so it
is never safe to use.  Our libc did not build getpw().
