aom_configure.cmake: fix flag propagation w/Android NDK <r23

Prior to r23, or with ANDROID_USE_LEGACY_TOOLCHAIN_FILE set,
android.toolchain.cmake would set normal (non-cache) versions of
variables like CMAKE_C_FLAGS_RELEASE which would mask the ones added to
the cache variable in add_compiler_flag_if_supported(), etc. As a
workaround we add everything accumulated in AOM_C/CXX_FLAGS to the
normal versions. This could also be addressed by reworking the flag
tests and adding the results directly to target_compile_options() as in
e.g., libgav1, but that's a larger task.
