bpf: fixed template for neg (added second operand)

This patch fixes define_insn for "neg" to support 2 operands.
Initial implementation assumed the format "neg %0" while the instruction
allows both a destination and source operands. The second operand can
either be a register or an immediate value.

gcc/ChangeLog:

	* config/bpf/bpf.md: fixed template for neg instruction.
