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.
Fixes: daabb2b098e0 ("bpf/tests: add tests for cpuv4 instructions")
