recipes-devtools: Add uefi-firmware-parser Python module

[theopolis]

I promised this a while back. ;)

In case anyone is wondering about the variances in naming:

• Recipe name: uefi-firmware-parser this is the project's name.
• PyPi module name: uefi_firmware this is what you import in python -c 'import uefi_firmware'.

This adds a pypi class, slightly modified from meta-python, which supports both name and hash-based source page downloading. PyPi seems to suggest the hash-bashed download from their S3 bucket so new packages should define a PYPI_PACKAGE_HASH. This is retrieved from the PyPi project page.

This recipe will install the python module for development but also a binary/entry-point (as documented on PyPi and the project README): /usr/local/bin/uefi-firmware-parser. The /usr/local/ PREFIX is determined by setuptools.
