uprobes/x86: Accept more NOP forms
Instead of only accepting the x86_64 nop5 chosen by the kernel, accept
any x86_64 NOP or NOPL instruction that is 5 bytes.
Notably, the x86_64 nop5 pattern is valid in 32bit apps and could get
compiler generated when build for i686 (which introduced NOPL). Since
the trampoline is x86_64 only, make sure to limit to x86_64 code.
