recipetool/devtool: Fix python egg whitespace issues in PACKAGECONFIG

Substitute expressions or whitespace from python egg requires.txt when
generating PACKAGECONFIG

Pysetuptools sees the uvicorn.egg-info/requires.txt as extra requirements.
Recipetool parses this information to generate the PACKAGECONFIG.
These extra requirements contain expressions and whitespace, which are not allowed in PACKGAGECONFIG.
This patch substitute them by hyphens to make PACKAGECONFIG parsable and readable.
Also adding an oe-selftest for this.

[YOCTO #14446]
