- Makefile.am: add root `test-quiet` target that maps to
`tests/quiet-test`, for completeness.
Ref: #22098
- tests/Makefile.am: drop unused remains of `MANFILES`.
Follow-up to fa3f889752#17463
Also replace the `distclean` target to delete `CLEANFILES`, otherwise
the CI dist job fails. (I'm not grokking why)
- tests/Makefile.am: sync up `tests` target with CMake, to pass `TFLAGS`
`-a`.
Follow-up to 904e7ecb66#19347
- tests/certs/Makefile.am: fix to clean generated certs via `CLEANFILES`
to comply with autotools documentation, which says the previously used
variable `DISTCLEANFILES` is meant for files created by `./configure`.
Ref: https://www.gnu.org/software/automake/manual/html_node/Clean.html
Follow-up to 44341e736a#16824
- tests/http/Makefile.am: add `./` prefix to glob passed to `rm -rf` on
clean, to avoid deleting unintented files, or pass unintended options.
