Oleg Nesterov 78a320542e 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.
