pkgin: Support multiple matching packages

pkgin searches for packages such as 'emacs' can return multiple matches,
the first of which is not guaranteed to match.  So, iterate through
found packages until we have an appropriate match.  Should we *not* find
a match, then return False indicating match failure.
