Christopher Haster 0990296619 Limited byte-level tests to native testing due to time 
Byte-level writes are expensive and not suggested (caches >= 4 bytes
make much more sense), however there are many corner cases with
byte-level writes that can be easy to miss (power-loss leaving single
bytes written to disk).

Unfortunately, byte-level writes mixed with power-loss testing, the
Travis infrastructure, and Arm Thumb instruction set simulation
exceeds the 50-minute budget Travis allocates for jobs.

For now I'm disabling the byte-level tests under Qemu, with the hope that
performance improvements in littlefs will let us turn these tests back
on in the future.
