[OE-core] [PATCH] rootfs_rpm.bbclass: fix a regression introduced by list_installed_packages change

[Ming Liu]

A regression was introduced by commit:190cb591 that it doesn't
consider the situation that some archs contain "_" originally, so it
results in issues when dealing with archs like qemux86_64, x85_64.

Added a conditional statment in to handle that case.
