largefiles: better handling of log from other working directory (issue4236)

When invoked from another directory, the matchers m._cwd will be the absolute
path. The code for calculating relative path to .hglf did not consider that and
log would fail with weird errors and paths.

For now, just don't do any largefile magic when invoked from other directories.
