suiteloader: add configuration option whether to load udebs.

Browse Source 
udebs do not have symbol versioned shlibdeps, thus it means that when
there is glibc in proposed, any packages built in proposed get a udeb
depends on the strictly higher version of glibc in proposed. This
leads to entaglement of the $world with glibc transition. Similar
story with glib, openssl, etc.

By setting the new configuration option to HAS_UDEBS = no, one can
make suiteloader not look at udebs, and thus use britney even when
installability of udebs is not required.
