build: replace the version patching with mesonpy approach

Under PEP 517, when the backend detects a VCS checkout, build does
roughly this:

 - Creates an isolated build environment
 - Exports the source tree using git archive
 - Builds the sdist from that exported tree

Thus the changes in meson.build are not picked up. Though the version
can be overwritten via the MESONPY_PROJECT_VERSION environment variable.
