fix(rpm): explicitly Provides user(cortex)/group(cortex)

dnf5 was silently rejecting neuron-0.1.3 with "Nothing to do" because
it had an unresolvable Requires. Inspection showed:

  Requires: user(cortex)               ← unversioned
  Provides: user(cortex) = <base64>    ← versioned only, no unversioned

rpm's sysusers provides-generator only emits the unversioned user()
provide when the u-line is minimal. Our sysusers.conf specifies GECOS,
home dir, and shell, which pushes the generator to versioned-only.
The matching Requires (auto-generated from %attr(,,cortex) on config
files) is unversioned, so resolution failed silently.

Explicitly declare Provides: user(cortex) and Provides: group(cortex)
to guarantee the unversioned forms exist. group(cortex) was already
emitted unversioned but adding it for symmetry and to protect against
future generator changes.
