t0001: allow implicit bare repo discovery for aliased-command test

8d1a744 (setup.c: create `safe.bareRepository`, 2022-07-14)
introduced a setting to restrict implicit bare repository discovery,
mitigating a social-engineering attack where an embedded bare repo's
hooks get executed unknowingly. To allow for that default to change at
some stage in the future, the tests need to be prepared.

This commit adjusts a test accordingly that runs `git aliasedinit`
from inside a bare repo to verify that aliased commands work there.
The test is about alias resolution, not bare repo discovery, so add
`test_config_global safe.bareRepository all` to opt in explicitly.
