rpm: Ensure compression parallelism isn't coded into rpms

Browse Source 
We don't want the compression thread numbers to be encoded into the rpm
since this results in the rpm not being deterministic. Add a patch
from Alex Kanavin which addresses this issue (was queued for rpm 4.17
but we need to fix this with 4.16 too).

(From OE-Core rev: 1ba0bf50c72f2506dfa507559c49a70e16cd5124)

Subject: [PATCH] build/pack.c: do not insert payloadflags into .rpm metadata
The flags look like '19T56' where 19 is the compression level
(deterministic), and 56 is the amount of threads (varies from one
host to the next and breaks reproducibility for .rpm).
Upstream-Status: Inappropriate [oe-core specific]
