If a file X is removed from CVS, it goes into the Attic directory, and
CVS reports it as 'no file X' but with status 'Up-to-date'. This is
misinterpreted an existing file when git-cvsexportcommit tries to commit a file
with the same name as one of these. This patch attempts to correctly identify
these files, so that new files with the same name can be committed.
Added a test to t9200-git-cvsexportcommit.sh, which tests that we can
re-commit a removed filename which remains in CVS's attic. This adds a
file 'attic_gremlin' in CVS, then "removes" it, then tries to commit a
file with the same name from git.
