tools: fix scan-build warnings in scmp_bpf_disasm

Delete the unused variable 'len' from scmp_bpf_disasm.

scan-build identified the following two warnings:

    scmp_bpf_disasm.c:304:10: warning: Although the value stored to 'len'
    is used in the enclosing expression, the value is never actually read
    from 'len'
            while ((len = fread(&bpf, sizeof(bpf), 1, file))) {

    scmp_bpf_disasm.c:441:10: warning: Although the value stored to 'len' is
    used in the enclosing expression, the value is never actually read from
    'len'
            while ((len = fread(&bpf, sizeof(bpf), 1, file))) {
