configure: allow to disable building of tools and test
This PR adds two set of options to the configure script:
--enable-png-tests/--disable-png-tests
and
--enable-png-tools/--disable-png-tools
By using this feature, a user will be allowed to build only library if
needed, which will be useful on platforms not able to build the tools
and/or the tests.
This PR leaves the existing behaviour as default setting, by building
both the tools and the tests if the options are not used.
CMakeLists.txt already supports this feature with the options PNG_TESTS
and PNG_EXECUTABLES. After this commit, Autotools will provide the same
feature.
