simpleperf: link simpleperf_ndk with dynamic libdexfile

This change let simpleperf_ndk always use libdexfile.so on the device
to read symbols from DEX files running on that device. Consequently,
libdexfile in AOSP can drop support for the old CDEX file format.

Also replace the CDEX file in testdata with a DEX file.

Test: run simpleperf_ndk manually on Android S+
