Initial attempt to run an application with hijack library on Android
platform.  Tested mostly on Android 6.x and 7.x.

The build process assumes that the android ndk toolchain is installed in
a host system as circle.yml does in its test.  arm32 build uses
alternate linker, stored in tools/lkl/bin directory, in order to avoid
the link issue (issue #59).

The CircleCI test infrastructure requires to use ubuntu 14.04 for this
test.

* Limitations
- aarch64 isn't tested on circleci due to difficulties on aarch64
emulator.
- bionic libc on android-24 emulator (arm32) doesn't call destructor, so
some of tests in hijack-test.sh fail.
- net.sh doesn't properly test network related issue.

Fixes #59.
