gnu: packages: 0ad: Tweak the build options.

Use the -C make option, rather than changing directory before the build
phase. Add config=release to the make flags as this might improve performance,
and verbose=1 as this might make the build process clearer.

Also remove --minimal-flags, as I don't quite understand what this does, but
using it seems to remove lots of flags that would be used by default.

* gnu/packages/games.scm (0ad)[arguments]: Add #:make-flags, remove the
  --minimal-flags argument from the configure phase, remove the 'chdir phase,
  and change the chdir argument in the install phase.
