kernel/configs: use .incbin directive to embed config_data.gz
This slightly optimizes the kernel/configs.c build.
bin2c is not very efficient because it converts a data file into a huge
array to embed it into a *.c file.
Instead, we can use the .incbin directive.
Also, this simplifies the code; Makefile is cleaner, and the way to get
the offset/size of the config_data.gz is more straightforward.
I used the "asm" statement in *.c instead of splitting it into *.S
because MODULE_* tags are not supported in *.S files.
I also cleaned up kernel/.gitignore; "config_data.gz" is unneeded
because the top-level .gitignore takes care of the "*.gz" pattern.
