[PATCH] .gitignore: add files produced by b4

[Andrey Zhizhikin]

b4 utility [1] is introduced by Linux Kernel developers and used to
fetch patches and patch series from lore.kernel.org and is proven
to be useful for U-Boot development. Detailed usage of the tool can be
read under post from the original author [2].

This tool fetches files from the list and populates the source folder
with additional files (*.cover and *.mbx) which are not ignored by git
and shown as newly added files.

Add those file patterns into .gitignore file, so they can be safely
skipped during changes attestation.
