earlyoom's Makefile attempts to detect the current version using git,
but we don't keep .git in its source, so this fails. We can however
set the VERSION environment variable to override this, as we now do.
They all depend on safe-money-0.7, but hackage2nix made them incorrectly
depend on safe-money-0.6
We should be able to remove this 'hack' as soon as the new Stackage LTS
comes out, as safe-money-0.7 will then be the default version.

To fix the linux build the patch `bsm-add-audit_token_to_pid.patch`
mustn't be applied during Linux builds, only for Darwin as it's an
Apple-only fix.
The compiler failure occurred because `audit_token_t` is part of
`<mach/mach.h>` which is not available on Linux.

The original build broke with the following linker issue:
```
CXXLD _PythonMagick.la
/nix/store/h0lbngpv6ln56hjj59i6l77vxq25flbz-binutils-2.30/bin/ld: cannot find -l-L/nix/store/4gh6ynzsd5ndx37hmkl62xa8z30k43y1-imagemagick-6.9.9-34/lib
collect2: error: ld returned 1 exit status
```
This happens since `BOOST_PYTHON_LIB` wasn't set properly, however
`_PythonMagick.la` was linked with `-l$(BOOST_PYTHON_LIB)
$(MAGICK_LIBS)`. With an empty `BOOST_PYTHON_LIB` the linker got
confused.
To work around this, the `boost` library directory needs to be specified
explicitly. To ensure that the changes take effect, the original
`configure` script shipped with `$src` needs to be removed and recreated
using the `autoreconfHook`.
Additionally the `imagemagick` license (https://spdx.org/licenses/ImageMagick.html)
needs to be added to `lib/licenses.nix` to document the proper license
of `pythonmagick` in the meta section.

Moves `mahotas` out of `python-packages.nix` into its own file and fixes
broken test cases by skipping them using nosetest's `@nottest`
annotation.
These tests broke from time to time in a sandbox and are therefore
considered impure.
