libretro-picodrive: fix build error

The environment variable "R" leaks into the Makefile,
if it is set the build will fail. eg

export R=12345
scripts/build libretro-picodrive
...
make: *** No rule to make target '12345pico/pico.o', needed by 'picodrive_libretro.so'.  Stop.

Clear the variable before calling make to fix this issue
