swc-windows-installer.py: Generalize update_bash_profile

And rename from make_bash_profile now that we're appending instead of
creating (since c5d5414, Append exports to end of .bash_profile
instead of overwriting, 2013-09-19).

This more general form can be used to add even more paths, for example
our IPython and nosetest entry points.
