kvm-unit-tests: bump version to fix build issue

Since binutils commit 1a9ccd70f9a7 ("Fix the linker so that it will not
silently generate ELF binaries with invalid program headers. Fix readelf
to report such invalid binaries.") the behaviour has changed and
binutils tries to create a program header segment for which there is no
space. Thanks to Nicholas Piggin and his patch to Linux:
https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?h=next&id=ff45000fcb56b5b0f

Cedric fixed this in kvm-unit-tests commit 95062c20790d ("powerpc: add
-n to LDFLAGS") so bump to that version.

Since the patch 0001-remove-werror.patch needs to be adjusted, we take
this opportunity to reformat is as a Git patch.
