feat(Makefile): add flash_glymur/ target

Add a new target that downloads the Glymur firmware and extracts it in a
flash_glymur/ directory. This allows for autocompletion thanks to
Makefile targets and allows to do the following and get what one would
expect:

	$ make flash_glymur/bootfw1.bin
	$ # or simply:
	$ make flash_glymur/
