the agent prints the daemon's version, from the constant the packaging reads

The agent answered --version with "fingerprintd-agent 0.2.2", the string
it was written with, while the daemon's constant went 0.2.3, 0.2.4, 0.2.5:
the subpackage carried the package's version and reported another. The
constant moves from main.cpp into the module both products import, with
its note on what a bump publishes; the two scripts that derive pkgver
from it, the APKBUILD's header and the CI comment name the new file. The
APKBUILD's own pkgver stays a hand-kept copy, which a bump changes too.
