bitbake: fetcher: Fixed remote removal not throwing exception.

Before this fix it is assumed that the removal of the
remote can only fail because there is not remote to remove. This
is a false assumption. Example error which would be ignored:

git -c core.fsyncobjectfiles=0 remote rm origin failed with exit code 1, output:
Note: A branch outside the refs/remotes/ hierarchy was not removed;
to delete it, use:
  git branch -d master
error: could not lock config file config
error: Could not remove config section 'remote.origin'

Due to the masking of this error a stranger error will be
presented to the user, because this time we do not mask the
exception:

git -c core.fsyncobjectfiles=0 remote add --mirror=fetch origin https://github.com/ptsneves/tl-wn722.git failed with exit code 128, output:
fatal: remote origin already exists.

The most likely reason that the remote cannot be removed nor
modified is that the DL_DIR/git2 does not have permissions
compatible with the user running bitbake.
