Use the exact current version in obtainMesonOutput

Currently this trims '0.48.0.dev1' to '0.48.0', and then requires exactly
that version in the generated meson.build for the test.

Just use the exact version.

Also only use a 'project(meson_version:)' constraint in the generated
project if a version is specified

Also remove unused grab_leading_numbers
