configs: Remove check for kernel in fs.py.
It is *not* true that a kernel is required in FS mode. For example,
in SPARC, gem5 is set up to run actual system firmware which will load
a kernel from the disk image. Other systems can run in a bare metal
mode where they also have no kernel.
If a configuration requires a kernel, it should check for it in C++
where there context lives, not globally in fs.py.
