cmd/headscale: migrate tests from check.v1 to testify

Convert config loading tests from gopkg.in/check.v1 Suite-based testing
to standard Go tests with testify assert/require.

Changes:
- Remove Suite boilerplate (Test, Suite type, SetUpSuite, TearDownSuite)
- Convert TestConfigFileLoading and TestConfigLoading to standalone tests
- Replace check assertions with testify equivalents
