POSIX: don't allocate memory after forking.
Previously we would allocate memory in the child process. However, the
allocation might have happened while the malloc lock was held,
resulting in a deadlock.
This patch removes allocation from the child but probably makes Mac's
startup time slower until a Mac person can implement
dir_reader_posix.h.
TEST=Unittest for new code
