Estimates a path in host from a corresponding path in Android device.

For Android, dmprof.py should find symbol information from binaries in
the host instead of the Android device because dmprof.py doesn't run on
the Android device.  They are in different directories.  This change
estimates a path in the host from a corresponding path in the Android
device.
