Subject: [PATCH] Fix aerc breaking every time the package is rebuilt.

On NixOS, the SHAREDIR changes on every rebuild to the package, but aerc
fills it in as part of the default config and then installs that config
to the users home folder. Fix this by not substituting @SHAREDIR@ in the
default config until runtime.
