Fixing unicode error

[dl1ksv]

The updated toolchain.py fails if the output of shprint contains unicode characters.
This can happen if you use something like:

shprint(sh.cp, '-v', entry, self.ctx.get_libs_dir(arch.arch))

and results in:

File "/usr/lib64/python2.7/site-packages/python_for_android-0.3-py2.7.egg/pythonforandroid/toolchain.py", line 2312, in build_recipes
recipe.postbuild_arch(arch)
File "/usr/lib64/python2.7/site-packages/python_for_android-0.3-py2.7.egg/pythonforandroid/recipes/qt5base/__init__.py", line 118, in postbuild_arch
  shprint(sh.cp, '-v', entry,  self.ctx.get_libs_dir(arch.arch))
File "/usr/lib64/python2.7/site-packages/python_for_android-0.3-py2.7.egg/pythonforandroid/toolchain.py", line 187, in shprint
shorten_string(msg, msg_width), width=msg_width))
UnicodeEncodeError: 'ascii' codec can't encode character u'\u201e' in position 0: ordinal not in range(128)

This fixed by this patch.
