Disable close() ScopedFD hook for component builds

As described in b/342530259, libc hooks in shared library does not work
reliably. The motivation for this change is to enable -Bsymbolic for
libchrome builds in ChromeOS, which is broken right now due to another
interaction with RTLD_NEXT.

This change disables the close() hook and ownership enforcement on
component builds. It is worth noting that enforcement was working as
intended on component builds before, because for Chromium we control the
shared library dependency graph and libbase happens to always get loaded
before libc. If someone was relying on that, it is advised that they
move to testing on non-component build.
