classes/package: Use HOST_OS for runtime dependencies
The code was using TARGET_OS to try and detect what type of OS the
packages would be running on, but this is incorrect. TARGET_OS is the OS
for which the package will generate output (e.g. GCC output target or
GDB debugging target). The OS where the package will run is the HOST_OS.
Note that HOST_OS only differs from TARGET_OS when doing a
canadian cross compile, and even then in our case only when doing so for
a non-Linux host (e.g. MinGW).
Fix the code to use HOST_OS instead.
