[PATCH] Python run fail if env variable PYTHON_HOME is not set

[PATCH] Python run fail if env variable PYTHON_HOME is not set

[Cheng, Ching JenX]

BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=2041

In Platform\Intel\MinPlatformPkg\Tools\Fsp\RebaseFspBinBaseAddress.py
It will run another python code.
But if the environment variable "PYTHON_HOME" is not exist
and we didn't add any python's path to "PATH".
It will cause error because python command not found.

the error message as below:
'python' is not recognized as an internal or external command,
operable program or batch file.

So we set the python's path from which execute the python code
if PYTHON_HOME was not exist.

Re: [edk2-devel] [PATCH] Python run fail if env variable PYTHON_HOME is not set

[Chiu, Chasel]

Please correct subject as you are modifying edk2-platform files:  --subject-prefix="edk2-platforms: PATCH"
Also the RebaseAndPatchFspBinBaseAddress.py should be obsolete soon, so please focus on RebaseFspBinBaseAddress.py.
