pip_install_wheel: improved wheel filename guess

Rather than only use PYPI_PACKAGE as a guess, fall back on PN for cases
where a recipe does not inherit pypi.

Wheels can only have alphanumeric characters in the 'distribution'
name [1]. Any other characters are replaced with an underscore. Provide a
function to replace dash with underscore.
