Fix build-time Python configuration
Apply various fixes and tweaks to Python configuration logic implemented
in the "configure" script:
- Prevent PYTHON_INSTALL_DIR, which holds the value passed to the
--with-python-install-dir option, from being set to "unspec" by
default as this breaks installing Python modules when the
--with-python-install-dir option is not used.
- Make the --with-python-install-dir option also work when the Python
interpreter is specified explicitly (using --with-python=<...>).
- Remove dnspython dependency which was erroneously introduced in
commit 31b0dc1f20: no installed Python
module depends on dnspython, it is only used in system tests, for
which dedicated scripts exist that check whether dnspython is
available and act accordingly.
- Improve contents and placement of error messages.
- Reduce duplication of code checking Python dependencies.
- Use Autoconf macros AS_CASE() and AS_IF() instead of plain shell
code.
- Update comments. Capitalize the word "Python" when referring to the
language itself rather than a specific executable.
