package/openjdk: allow compiling without X11 support

Browse Source 
Added patches (17.0.12+7 and 21.0.4+7) to allow compilation
without X11 support.

0003-autoconf-libraries-drop-the-need-for-X11-in-headless.patch
is only needed for 21.0.4+7, 17.0.12+7 already has this commit:
f97ec359ec

Next to that, add a new option BR2_PACKAGE_OPENJDK_X11,
to allow compilation with both head and headless support.
