rootfs_rpm.bbclass: maybe no rpm postinst script

There maybe no rpm postinst script (e.g., core-image-minimal), then the
"*" is not expanded, and there would be error:

head: cannot open `rpm-postinsts/*' for reading: No such file or directory

Check whether it exists or not will fix the problem.

[YOCTO #3172]
