Ilpo Järvinen a8eba04777 selftests/resctrl: Fix feature checks 
commit 06035f0194 upstream.

The MBA and CMT tests expect support of other features to be able to
run.

When platform only supports MBA but not MBM, MBA test will fail with:
Failed to open total bw file: No such file or directory

When platform only supports CMT but not CAT, CMT test will fail with:
Failed to open bit mask file '/sys/fs/resctrl/info/L3/cbm_mask': No such file or directory

It leads to the test reporting test fail (even if no test was run at
all).

Extend feature checks to cover these two conditions to show these tests
were skipped rather than failed.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
