[CRIU] [V3 3/4] Android NDK: no index function in strings.h

[ning.a.zhang at intel.com]

From: Zhang Ning <ning.a.zhang at intel.com>

due to Android NDK's strings.h doesn't have index function.
Declare this function in CRIU, just like povit_root.

still need to provide index function implement, for link CRIU.
