Fix renaming PRODUCT and MANUFACTURER for Caterina devices like leonardo

[G33kLabs]

It works with that in the Makefile (all without quotes) :

USB_MANUFACTURER = MANUFACTURER_NAME
USB_PRODUCT = PRODUCT_NAME

[sej7278]

this seems to break cores that actually use these settings e.g. the adafruit ones, where they use quotes:

feather32u4.build.usb_product="Feather 32u4"
feather32u4.build.usb_manufacturer="Adafruit"

the makefile without your patch works fine if you also use quotes, which you should do anyway as the strings may have spaces:

USB_PRODUCT = "product with spaces"

Ok, will check you that tomorrow with electronics near.

Did you get a chance to check it with the real hardware?
