Fix buildifier for micromamba

[nettle]

Why:
Buildifier, unfortunately does not work under Micromamba environment
because buildifier scans (find) all subdirectories including bazel output base dir
inside micromamba dir and some files cannot be read there, so it causes error.

What:

• Add patches for buildifier to prune excluded locations
• Test for Bazel 6.5 and 7.7

Test:

source .ci/micromamba/init.sh
bazel test :buildifier_native

Addresses: #155, #163
