__cfi_slowpath[_diag] are available to NDK and VNDK clients

Browse source 
When a vendor lib (or vendor-available platform lib) is built with
sanitizer on, __cfi_slowpath_diag is required. However, when building
for those libs, the llndk stub of libdl.so is provided for them and
__cfi_slowpath_diag is not exposed to the stub. In order to make the
sanitizing build successful, expose the symbol.

These symbols are also exposed to NDK clients since we may want to CFI
for unbundled apps.

Test: BOARD_VNDK_VERSION=current m -j libstagefright_foundation.vendor
