  TRAVIS: Try suppressing warnings in system includes

For two reasons, SDL2 when compiling with Clang and Boost.Locale on
macOS.

Clang ignores the "/* fallthrough */" comments in the SDL2 includes
and then complains about unmarked switch-case-fallthroughs. The SDL2
search script doesn't mark the SDL2 directory as system.

The Travis CI macOS build VMs have Boost.Locale preinstalled in
/usr/local/ and this is not marked as a system include. The version
preinstalled used std::auto_ptr and Clang notes that this is
deprecated.

  Log Message:
  -----------
  BUILD: Disable -Wunused-const-variable

This one is enabled by -Wall in Clang, but not in gcc (at least not
for C++). The warning doesn't make sense for us, especially since we
sometimes leave in unused static const values for documentation
purposes, so let's disable it.

  Log Message:
  -----------
  BUILD: Disable -Wtautological-unsigned-enum-zero-compare

Whether an enum is signed or unsigned is implementation defined, so
this warning doesn't make any sense for us.
