[media] b2c2: use IS_REACHABLE() instead of open-coding it

The FE_SUPPORTED() macro is basically the same as IS_REACHABLE, except
that it causes a warning with gcc-7:

common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined]
common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined]
common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined]

Using IS_REACHABLE() to define it avoids the warning.

Fixes: 3785bc17 ("[media] b2c2: break it into common/pci/usb directories")
