lib.sh dependencies: support --reinstall argument

./mk dependencies debian --reinstall

Add --reinstall and it'll do:

apt-get install --reinstall

This can be useful when updating from a stable release
to a testing release. The variable, "reinstall" can be
configured for other distros, but it's currently only
configured for Debian-based distros.

Also, it can be anything. For example, you could add -y;
however, a 4th argument will not be accepted. For example,
you cannot do:

./mk dependencies debian --reinstall -y

If you do this, it'll only see --reinstall; similarly, if
you did this command:

./mk dependencies debian -y --reinstall

then -y would be passed, but not --reinstall. This is an
intentional design decision, in case you accidentally pasted
or subshelled something that outputted something undesirable,
to prevent possible abuse.
