largefiles: fix addremove with -R option

If a file was missing, the missing list contained a path relative to the repo.
When building the matcher from that list, the file name ended up concatenated to
cwd, causing the command to abort with '<file> not under root'.  This rebuilds
the missing list with paths relative to cwd.
