tests: Mock file i/o for linux_mtd and linux_spi tests

Browse Source 
This patch adds an init-shutdown test for linux_mtd. Since
linux_mtd is using file i/o operations, those are added to the
framework and mocked.

Another driver linux_spi which is also using file i/o, got an upgrade
in this patch, and it is now reading max buffer size from sysfs (using
mocked file i/o).

A good side-effect is that linux_mtd is the first test for opaque
masters, which is great to have in preparation for a change like
CB:56103 but for opaque masters.
