fix(rpm): derive the libcuda link stub from source (fixes undefined cu* symbols)

Browse Source 
The Fedora RPM build linked punktfunk-host against a synthesized libcuda stub
with a FROZEN symbol list baked into ci/fedora-rpm.Dockerfile. The priority-
stream work added cuCtxGetStreamPriorityRange / cuStreamCreateWithPriority /
cuStreamSynchronize / cuMemcpy2DAsync_v2, which weren't in that list, so the
link failed with "undefined symbol".

build-rpm.sh now regenerates /usr/lib64/libcuda.so.1 from every cu* symbol the
host source references (grep of crates/punktfunk-host/src), before rpmbuild — so
a new cu* call can never silently break the link again. Self-maintaining and
needs no builder-image rebuild (it supersedes the Dockerfile's frozen stub).
Verified the 23 extracted symbols compile and cover the 4 that were undefined.

Also fix the bogus %changelog weekday (Sun -> Mon, Jun 15 2026 is a Monday) that
rpmbuild warned on.
