mesa: Avoid installing khrplatfrom.h when not needed

Fix the conflict between mesa and userland (when former is used to
provide GL and letter used to provide EGL+GLES) by not installing
khrplatform.h header when its not needed.

+Subject: [PATCH] mapi: Only install khrplatform.h with EGL or GLES
+
+When mesa is built with "--disable-egl --disable-gles1
+--disable-gles2" the KHR platform headers are not needed.
+
+Not installing the header when not needed allows using mesa for GL
+and another implementation for GLES+EGL (as is done in practice with
+userland on raspberrypi).
+
+Upstream-Status: Pending [waiting for test results before sending]
