A few fixes for program messages

[Sven Joachim <svenjoac@gmx.de>]

Hi,

while working on the German dpkg translation I noticed a typo in
src/filesdb.c and three examples of clumsy/slightly incorrect English in
scripts/update-alternatives.pl.  Not being a native speaker nor terribly
familiar with update-alternatives myself, I may of course be wrong, so I
leave this to your judgment:

Unless "statusoverrides" is a /terminus technicus/ of its own (I don't
think it is), it should probably be changed further to
"status overrides".
