LU-5845 build: add support for SUSE_LINUX-12 .spec file

Add the SLES 12 .spec file.  Do not include the e2fsprogs lfsck
feature for this distro, since the Lustre LFSCK is a functional
replacement and is much faster than using the external db4
databases used by lfsck.  That also avoids the ongoing dependency
problem with db4 RPM being named differently on every distro.
