[Mesa-dev] [PATCHv2] configure: cleanup libudev handling

[Emil Velikov]

Add the explicit note about the required version during configure.
Require the same version (151) of udev when building the pipe-loader.
Mention the udev version requirement in GBM Requires.private.

v2: Resolve a couple of silly typos. Spotted by Ilia
