In selftests/amd-pstate, distro `perf` is used to capture `perf stat`
while running microbenchmarks. Distro `perf` is not working with
upstream kernel. Fix this by providing an option to give the perf
binary path.

In selftests/amd-pstate, tbench and gitsource microbenchmarks are
used to compare the performance with different governors. In current
implementation the relative path to run `amd_pstate_tracer.py` is broken.
Fix this by using absolute paths.

Add gitsource.sh trigger the gitsource testing and monitor the cpu desire
performance, frequency, load, power consumption and throughput etc.
1) Download and tar gitsource codes.
2) Run gitsource benchmark on specific governors, ondemand or schedutil.
3) Run tbench benchmark comparative test on acpi-cpufreq kernel driver.
4) Get desire performance, frequency, load by perf.
5) Get power consumption and throughput by amd_pstate_trace.py.
6) Get run time by /usr/bin/time.
7) Analyse test results and save it in file selftest.gitsource.csv.
8) Plot png images about time, energy and performance per watt
for each test.

Split basic.sh into run.sh and basic.sh.
The modification makes basic.sh more pure, just for test basic kernel
functions. The file of run.sh mainly contains functions such as test
entry, parameter check, prerequisite and log clearing etc.
Then you can specify test case in kselftest/amd-pstate, for example:
sudo ./run.sh -c basic. The detail please run the below script.
./run.sh --help
