ctail: fix build on ML due to apr-1-config

Ctail and Serf suffer from the ML bug where `apr-1-config --cpp`
returns a non-existent path. Serf is fixed. Add the same changes
to Ctail where `CPP` and `APR_LIBTOOL` get sane values, where
there are new deps on `libtool` and `automake`, and where
XCode-only installs get help finding the apr includes. Also
change from manual compile commands into using their Makefile
because it works correctly and was doing the same thing basically.
By using the `Makefile` we also get all the `apr-1-config --libs`
brought in which may be different for SL vs L vs ML.

cf. #13891
Fixes #14313

Closes #14451.
