Fix braindead symbol versioning issue where applications that linked

Browse Source 
against libapparmor::change_hat would be linking against
change_hat@IMMUNIX_1.0 rather than change_hat@APPARMOR_1.0 (the
preferred version).

Remove -module to prevent linking portability warning when building
mod_apparmor.

Use RPM_OPT_FLAGS for CFLAGS when building rpms.
