Revert "[zircon][utest][pager] Exclude root-resource tests at runtime, not compile"

This reverts commit fd4a750800aeabfe01beb0062a1eee7c873c3608.

Reason for revert: Landed accidentally via topic CQ snafu!

Original change's description:
> [zircon][utest][pager] Exclude root-resource tests at runtime, not compile
> 
> Rather than using #ifdef BUILD_COMBINED_TESTS to decide whether the
> root resource handle will be available for tests that need it, instead
> use a weak symbol for get_root_resource and check it at runtime.
> This obviates the need to compile the test sourcce file differently for
> the integrated and standalone cases.
> 
> Bug: BLD-325
> Test: CQ
