android: Fix build error for Android

Android uses functions and defines from sys/capability.h which
requires additional include. However file capability.h shows up
in bionic in version Android 4.3, therefore we do check
PLATFORM_SDK_VERSION to no break builds of previous Android versions.
In previous Android version unistd.h contain this functionality.
