Title: Fix is_package_installed method of YumRole

The previous implementation could lead to not expected behavior.

Eg: role.is_package_installed('gcc') would match also to 'libgcc',
whereas 'libgcc' doesn't depend on gcc, the method would return True
even if gcc isn't installed.

The new implementation makes use of:
rpm -qa

Which is a very strict match.
