Non-SFI Mode: Add disable_nacl_untrusted==0 to the condition of nacl_helper_nonsfi creation.

nacl_helper_nonsfi is actually NOT the untrusted code, but this is built by
the PNaCl toolchain, which is native_client untrusted toolchain in the
context of common.gypi. In order to keep the other _nacl.gyp files simple,
this CL adds disable_nacl_untrusted==0 guard to the nacl_helper_nonsfi
creating condition, so that it does not cause the gyp error due to depending
on missing targets when disable_nacl_untrusted is set to 1.

BUG=358465
TEST=Ran trybots.
