more monster alignment

Simplify is_lminion(); as a result, several source files no longer
need access to epri.h.  (mondata.c already could have lived without it;
eshk.h as well.)

Makefile dependency changes:
  mondata.{c,o} -- doesn't need epri.h or eshk.h
  monmove.{c,o} -- doesn't need epri.h
  wizard.{c,o}  -- ditto
  pline.{c,o}   -- ditto (yesterday's patch)
