Exclude wrap_memcpy.cc from BUILD.gn unconditionally

Exclude wrap_memcpy.cc from BUILD.gn unconditionally

wrap_memcpy.cc is problematic for several reasons:
 * It's not used in the gn build, since no one sets up -Wl,-wrap,memcpy.
 * When it's in the main binary as a part of source_set, -Wl,-wrap,memcpy
   introduces infinity recursion on memcpy.
 * That causes link failure on LLD build in Chromium tree.

BUG=661171

Thanks!
I think I don't have the permission to land this. Could you do it for me?

Hm, I had some weird errors from git cl land when running on this issue. It
seems that commit landed successfully, but it has me as an author, and this
issue was not updated. I was probably using 'git cl' wrong, but other than this,
it should be fine:

Thanks again! No problem. So, let me close this and roll it.
