Avoid ignoring files actually in our tree, and ignore some generated
files that were not being ignored previously.

This file is specifically ignored by our .gitignore.  Brian added this
ignore on 2013-06-06 but neglected to remove the file.  I've now
bulid-tested without the file to be sure that it is indeed generated
correctly and so can be removed safely.

freeswitch.serial is used by ZRTP as a ZID, so it should not be shared
between systems and definitely should not be distributed as a default
value by us.

Note that we don't actually support building mod_spidermonkey for
Debian at the moment.

Note that we don't actually support building mod_managed at this time
for Debian.
