LU-9775 Look for kernel-devel in /usr/src/kernels

If one is building in a build [ch]root such as mock provides, one may
not have the kernel installed which corresponds to $(uname -r).  In such
a case, also try to look for the kernel-devel in /usr/src/kernels/ and
just build for the latest one.  Ideally there is only one installed in any case.
