[CI:BUILD] packit: handle builds for RC releases

The `version_no_tilde` rpm macro correctly handles both `vX.Y.Z` and
`vX.Y.Z-rcN` git tags. Using this macro instead of `version` will soon
allow Packit to handle RC builds correctly.

Accompanying change in Packit to land soon:
packit/packit#2149

[NO NEW TESTS NEEDED]
