rpm: fix a endian incompatible error in generating tag
A flaw was found in the way rpm generating arbitrary tags, which leads to a
incorrect query result, this issue is introduced by a incompatible endianess
when the generating process is executed on different architectures.
This patch resolves it by taking the byte order that host uses.
