[PATCH 3.19.y-ckt 157/170] kbuild/mkspec: fix grub2 installkernel issue

[Kamal Mostafa]

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

From: Jiri Kosina <jkosina at suse.cz>

commit c8b08ca558c0067bc9e15ce3f1e70af260410bb2 upstream.

mkspec is copying built kernel to temporrary location

	/boot/vmlinuz-$KERNELRELEASE-rpm

and runs installkernel on it. This however directly leads to grub2
menuentry for this suffixed binary being generated as well during the run
of installkernel script.

Later in the process the temporary -rpm suffixed files are removed, and
therefore we end up with spurious (and non-functional) grub2 menu entries
for each installed kernel RPM.

Fix that by using a different temporary name (prefixed by '.'), so that
the binary is not recognized as an actual kernel binary and no menuentry
is created for it.
