build: allow package to be built for all variants

This allows a package to be rebuilt for all different VARIANTs.
To do so, set VARIANT=*.

The wpa-cli package is not getting built after changes made by
19aae94 [build: avoid rebuilds of unset VARIANT packages], because
wpa-cli is only built when compiling a variant that includes
supplicant support, and the first selected variant may not build it.
