cocci: split off include-less "tests" from SPATCH_FLAGS

Amend the "coccicheck-test" rule added in f7ff659 (cocci: add a
"coccicheck-test" target and test *.cocci rules, 2022-07-05) to stop
using "--all-includes". The flags we'll need for the tests are
different than the ones we'll need for our main source code.
