Add /usr/local/bin to default PATH under strict action env

With this change, when --incompatible_strict_action_env is on but no override for PATH is available, the default PATH will include /usr/local/bin. This allows Python 3 to be on PATH on mac, which is important for the autodetecting Python toolchain.

Without this change, users can still use --action_env=PATH[=...], but that doesn't work in all cases (e.g. genrules that are themselves built in the host config).

Fixes #8536. Confirmed that this fixes the failure seen in https://bugs.chromium.org/p/gerrit/issues/detail?id=10953.

RELNOTES: When `--incompatible_strict_action_env` is enabled, the default `PATH` now includes `/usr/local/bin`.
