config, x86: move kernel specification from tests to FSConfig.py

For some reason, the default x86 kernel is specified in
tests/configs/x86_generic.py and not in configs/common/FSConfig.py,
where the kernels for all the other ISAs are.  This means that
running configs/example/fs.py for x86 fails because no kernel
is specified.  Moving the specification over fixes this problem.

There is another problem that this uncovers, which is that going
past the init stage (i.e., past where the regression test stops)
fails because the fsck test on the disk device fails, but that's
a separate issue.
