As it expects Bash to be at `/bin/bash`, the current implementation
fails to execute on NixOS, given that there bash is in a non-standard
path (i.g. `/nix/store/<hash>-bash-interactive-<version>/bin/bash`).
This patch specifically changes `/bin/bash` paths to use `/usr/bin/env bash`,
which should give the correct path in every Unix system.

This removes all other Bazel test commands, so all tests can be again
tested with `bazel test ...`.
Also, fixes linux-arm64 glibc tests. Until now they've worked only in
CI. Now they work everywhere I tried.
