FindBISON: Add COMMAND_EXPAND_LISTS to remove empty arguments

Browse Source 
When using generator expressions in the COMPILE_FLAGS argument, and the
generator expression expands to an empty string, command gets an empty
argument with double quotes where GNU bison command-line tool errors out
with `/usr/bin/bison: extra operand` error. This removes empty arguments
from the created bison command.
