hostapd: avoid unnecessary package rebuilds

Package hostapd-common is a dependency of every other package defined in
hostpad Makefile.  It is currently built next to the bottom of that
Makefile's package list.

If you run make back to back, then check-compile will compare the
hostapd-common timestamp to the variant being compiled, to decide if the
varint needs to be rebuilt or not.  Since the hostapd-conf package is
built towards the end of the list, it will be newer than most of the
variants, causing unnecessary package rebuilds.

Move it to the top, so that its timestamp will be older than dependent
packages, avoiding unnecessary rebuild of every selected variant.
