tmac/an-ext.tmac: Fix .ME/.UE portability issue.
* tmac/an-ext.tmac (.ME, .UE): Fix portability issue. While widely
supported(1), the \$* escape is not documented in CSTR #54. If groff
is not the typesetter, append macro arguments using \$1, \$2, ..., \$9
instead. This is an edge case; .ME and .UE are documented as
supporting only one argument anyway.
(1) AT&T troff (obviously) and Plan 9 troff don't support it. Heirloom
Doctools troff added support in its 050816 release (August 2005) and
neatroff in a commit on 2018-03-02.
