[PATCH] meson.build: Use -Wno-undef only for SDL 2.0.8 and older

[Thomas Huth <thuth@redhat.com>]

There is no need to disable this useful compiler warning for
newer versions of the SDL anymore.

This also enables the printing of the version number with
newer versions of the SDL in the summary of the meson output
again.
