make-tag: Remove MSVC check

The MSVC check is no longer necessary as of bitcoin/bitcoin#23198,
which generates the version information by parsing `configure.ac`.

(we like want to backport that 22.1 as well, before the next
minor release there, to avoid needing three variants of the make-tag
script)
