egl: Improve the debugging of gbm format matching in DRI configs.

Previously the debug would be:

libEGL debug: No DRI config supports native format 0x20203852
libEGL debug: No DRI config supports native format 0x38385247

but

libEGL debug: No DRI config supports native format R8
libEGL debug: No DRI config supports native format GR88

is a lot easier to understand.
