dummyflasher.c: Drop useless macros

The `EMULATE_CHIP` and `EMULATE_SPI_CHIP` macros are unconditionally
defined as `1`, with no way to change their values. Since this means
that the code never gets build-tested using other values, drop these
noisy macros.

TEST=Build with `make distclean && make VERSION=none -j` with and
     without this patch, the flashrom executable does not change.
