Use HGPLAIN instead of HGRCPATH in VCS_INFO_get_data_hg
Fixes prompt indicator in case if the repository requires a non-default
feature. With HGRCPATH, it results in:
abort: repository requires features unknown to this Mercurial: ...
(see
https://mercurial-scm.org/wiki/MissingRequirement for more information)
Which, in turn, results in "default" getting reported regardless of what
the current state of the repo is.
