Evgeniy Stepanov 6153377219 [asan] Fall back to /proc/$PID/maps on Android L. 
dl_iterate_phdr is somewhat broken in L (see the code for details).
We add runtime OS version detection and fallback to /proc/maps on L or earlier.
This fixes a number of ASan tests on L.

Evgeniy Stepanov ce29096614 [asan] Fix dynamic-runtime tests. 
They are not part of check-all :(

This change adds sized-delete operators to the version list, and disables the
hack that excluded versioned symbols from the dynamic list - this is not an
issue in this case.
