[LLD] [MinGW] Reinstate the former spelling in the version message (l…

…lvm#97698)

0f9fbbb changed the version printouts.
This broke linker detection in Meson, when disambiguating between the
ld.lld and lld-link interfaces, in

https://github.com/mesonbuild/meson/blob/1.4.1/mesonbuild/linkers/detect.py#L67,
which checks for the string "(compatible with GNU linkers)" including
the parentheses.

Reinstate the parentheses in the printout here, for compatibility with
Meson. The printout looks a little odd in this form, "LLD 19.0.0
(https://github.com/llvm/llvm-project
173514d) (compatible with GNU
linkers)", but works with Meson.

The Meson check is loosened in mesonbuild/meson#13383,
but existing versions of Meson with the too strict check will be around
for quite some time, so we should only change LLD to the new form once
older versions of Meson aren't used for these targets any longer, i.e.
earliest within a few years.
