In 'NOFENTRY_ARGS' test case for syntax check, any offset X of
`vfs_read+X` except function entry offset (0) fits the criterion,
even if that offset is not at instruction boundary, as the parser
comes before probing. But with "ENDBR64" instruction on x86, offset
4 is treated as function entry. So, X can't be 4 as well. Thus, 8
was used as offset for the test case. On 64-bit powerpc though, any
offset <= 16 can be considered function entry depending on build
configuration (see arch_kprobe_on_func_entry() for implementation
details). So, use `vfs_read+20` to accommodate that scenario too.
