LU-6300 build: Kernel string mismatch for ppc64 in RPMs

LU-6300 build: Kernel string mismatch for ppc64 in RPMs

The macro in the kernel RPMs for ppc64 provided
by Redhat describing the kernel version supported,
mismatch the content of the macro of the Lustre kernel
client modules for ppc64 describing the required
kernel. This leads to unresolved dependency errors
during installation of the Lustre client modules
although the kernel versions match actually.

While Redhat uses the convention:

kernel = <major-number>-<minor-release-number>.el6

the following string is used in Lustre client RPM
for the required kernel version:

kernel = <major-number>-<minor-release-number>.el6.ppc64

The patch will remove the trailing string '.ppc64' in
macro 'krequires' defined in the lustre specfile
describing the software dependeny.
