build: Fix ninja warning message on Windows

We currently run 'git describe --match' to obtain the current version,
but meson doesn't properly quote/escape the pattern string on Windows.

As a result, "fatal: Not a valid object name .ninja_log" is printed
when compiling on Windows systems. Compilation still works, but the
warning is annoying and misleading.

Currently we don't actually need the pattern matching functionality
(which is why things still work), so simply remove it as a workaround.
