uprobes: Change valid_vma() to demand VM_MAYEXEC rather than VM_EXEC uprobe_register() or uprobe_mmap() requires VM_READ | VM_EXEC, this is not right. An apllication can do mprotect(PROT_EXEC) later and execute this code. Change valid_vma(is_register => true) to check VM_MAYEXEC instead. No need to check VM_MAYREAD, it is always set.
