modprobe: fix for blacklisting

The patch makes the order of the alias/blacklist in modprobe.conf
irrelevant (like module-utils' modprobe). In first patch the alias had
to be defined before the blacklist which caused problems because the
modprobe.conf file is read before /lib/modules/*/modules.alias.

The attatched patch will mark the blacklisted module itself rather than
trying to find the alias that points to the blacklisted module and test
this flag later in the alias resolving stage.

last: make its output more like "standard" last (aka "fancy last").
The main difference is that LOGIN lines are still shown by non-fancy one.
