phosphor-tiny: Reduce python.bb .py files

Only the .pyc files are needed from the python recipe.
There was some discussion of natively supporting this
in the python recipe within this bug:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=6434

But nothing ever came of it so for now bbappend a file
that removes the unneeded .py files during install.

This saves us 800KB of rofs space.

Testing: Verified the python apps still started without
issue in QEMU.

Resolves: openbmc/openbmc#3372
