Weaken sel_ldr dependency on old x86 validator.
Weaken sel_ldr dependency on old x86 validator.

It appears that all sel_ldr needs from old x86 validator is NaClCopyInstruction
function in validator_x86/nccopycode.c. Despite that, gyp files specify
dependency on entire old validator. This CL fixes it.

Technically, src/trusted/validator_x86/validator_x86.gyp:nccopy_x86_32(64) is
not part of old validator, so it makes sense to move it some place else. I'm not
doing it right now because it would require updating references in old
validator, which is subject to deletion anyway.
