bpf, docs: Fix the description of 'src' in ALU instructions
An ALU instruction's source operand can be the value in the source register or the 32-bit immediate value encoded in the instruction. This is controlled by the 's' bit of the 'opcode'. The current description explicitly uses the phrase 'value of the source register' when defining the meaning of 'src'. Change the description to use 'source operand' in place of 'value of the source register'.

otherwise identical operations. ``ALU64`` instructions belong to the
