match: move entire uipath() implementation to basematcher
Even though most matchers will always want to use the relative path in
uipath(), when we add support for intersecting matcher, we will want
to control which form to use for any kind of matcher without knowing
the type (see next patch), so we need the implementation on the base
class.
Also rename the attribute from "pathrestricted" to "relativeuipath"
since there actually are cases where we match everything but still use
relative paths (like when the user runs "hg files .." from inside
mercurial/).
