16k: core: Enable TARGET_NO_BIONIC_PAGE_SIZE_MACRO by default on Android V targets

Enabling TARGET_NO_BIONIC_PAGE_SIZE_MACRO implies those targets no
longer rely on the `PAGE_SIZE` bionic macro. Page size would be queried
at runtime using getpagesize() / sysconf(_SC_PAGE_SIZE).

Test: lunch <target> && get_build_var TARGET_NO_BIONIC_PAGE_SIZE_MACRO
