Move code to create directories in master to after daemon core starts up.
Move code to create directories in master to after daemon core starts up.

Because creating the directories needs a call to get_condor_uid(), we
cannot do this in main() else the condor_master will never switch to
user condor!  Moving this code to pre_command_sock_init instead, which
should be early enough but late enough that the priv system is setup.
Also fixed a typo on the SPOOL permission.  HTCONDOR-73
