util/chromeos/extract_blobs: Add support for command line params
Add support for taking the ifdtool platform parameter via the cmd line, as well as the output directory. Add double quotes around variables as needed. Add help output describing new parameter options. TEST=run script against images from skl, adl, and mtl platforms. Verify no warning from ifdtool that platform is unknown.
