Add _android files for building DartVM on Android
...
Split directory_posix -> directory_(android|linux|macos)
This allows us to cleanly make Android-specific changes to
directory_android.cc
Copy all _linux files to _android files and edit as needed to account
for the differences between Linux and Android:
+ getcwd(0, NULL) doesn't work on Android, have to emulate
+ Android doesn't have a '/tmp' directory, have to emulate
+ Android doesn't provide mkdtemp(), have to emulate.
+ Small differences in the available system include files.
+ Use pthread_cond_timedwait_monotonic instead of
pthread_condattr_setclock
