filemerge: store error messages in module variables

Copytracing may be disabled because it's too slow (see
experimental.disablecopytrace config option). In that case user may get errors
like 'local changed FILE which other deleted'. It would be nice to give user a
hint to rerun command with `--config experimental.disablecopytrace=False`. To
make it possible let's extract error message to variables so that extension may
overwrite them.
