[Buildroot] [PATCH] support/download: don't be over-remove file from git archives

[Yann E. MORIN]

When we now manually create git archives, we remove all .git-related
files. However, we also exclude empty directories.

This means that a directory which only had a .gitignore file is excluded
from the archive.

Fixes:
