add fix to golangci linter hook

[ocofaigh]

Description

pre-commit are failing when they run inside the renovate docker image:

[INFO] Installing environment for local.
[INFO] Once installed this environment will be reused.
[INFO] This may take a few minutes...
An unexpected error has occurred: FileNotFoundError: [Errno 2] No such file or directory: '/tmp/containerbase/cache/.cache/pre-commit/repo608oo3ko/golangenv-system/.install_state_v1staging'
Check the log at /tmp/containerbase/cache/.cache/pre-commit/pre-commit.log

Looks like same issue was reported in pre-commit/pre-commit#3219 and the suggested fix was to change to use system. I tested locally and in the image and it seems to work.
