bpf: Remove test for MOVSX32 with offset=32

bpf: Remove test for MOVSX32 with offset=32

MOVSX32 only supports sign extending 8-bit and 16-bit operands into 32
bit operands. The "ALU_MOVSX | BPF_W" test tries to sign extend a 32 bit
operand into a 32 bit operand which is equivalent to a normal BPF_MOV.

Remove this test as it tries to run an invalid instruction.
