Summary:
This is a new attempt at D38706, which had 2 issues.
The first one was that it broke TSan, because `sanitizer_errno.h` was not
directly included in `tsan_mman.cc`. This fixes the include.
The second one was that it broke the nolibc build, because `__errno_location`
couldn't be found. This adds the new .cc to the libcdep list instead of the
base one.

Summary:
The fact that `sanitizer_allocator_checks.h` is including `sanitizer_errno.h`
creates complications for future changes, where it would conflict with `errno.h`
definitions on Android and Fuchsia (macro redefinition).
By moving the portion that sets errno in the checks to a separate compilation
unit, we avoid the inclusion of the header there, which solves the issue.
Not that it is not vital to have that function in a header as it is called as a
result of an unlikely event, and doesn't need to be inlined.
