Add support to match aliases for uncore PMUs.
Since we cannot rely on the PMUs being present on the host system, use
fake PMUs.
The following conditions in the test are ensures:
- Expected count of aliases created
- All aliases can be matched to an expected alias in
perf_pmu_test_pmu.aliases
This will catch the condition fixed in commit c47a5599ed ("perf tools:
Fix pattern matching for same substring in different PMU type"), where
excess events were created for a PMU. It will also fix the scenario
inadvertently broken there, where no aliases were created for aliases
with multiple tokens.

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.
