function_graph: Rename BYTE_NUMBER to CHAR_NUMBER in selftests

The function_graph selftests checks various size variables to pass from
the entry of the function to the exit. It tests 1, 2, 4 and 8 byte words.
The 1 byte macro was called BYTE_NUMBER but that is used in the sh
architecture: arch/sh/include/asm/bitops-op32.h

Just rename the macro to CHAR_NUMBER.
