serve: make tests compatible with chg

chg only supports 'hg serve' when the options to the serve command
follow the 'hg serve'. For example, 'hg -R <repo> serve ..' is unsupported.
This leads to issues with chg running for the following tests:

 - test-bundle2-exchange.t
 - test-clone-uncompressed.t
 - test-hgweb-csp.t
 - test-http-bad-server.t
 - test-http-bundle1.t
 - test-http-protocol.t
 - test-http.t

There was an effort made earlier to fix this issue for chg and the tests were
fixed to confirm to the compatible pattern. But the new tests did not take care
of the same and hence, fail. Hopefully, there will be continuous build setup
for chg after all tests are made compatible with chg so that we can avoid such
issues.

Test Plan:
Ran the aforementioned tests with and without '--chg' option.
