seafile-seahub's build is a mess.
It hijacks some OpenWrt mk files into the build.
This can be avoided by provided some of the required parameters via
env-vars and patching the env-vars into the build.
Which is what this patch does.

(cherry-picked from commit cf99755444)
Switch to codeload for simplicity and easier package bumping.
Added dependency on pytz on build time as django-admin requires it.
