psutil's setup currently gates Linux sources behind
``sys.platform.startswith('linux')``. On Termux Python reports
``sys.platform == 'android'``, so setup aborts with
"platform android is not supported" despite compiling fine when using the
Linux source path.
We patch only the extracted build tree used for this install attempt;
nothing is persisted in the repository.
