This patch changes the default value of 'dict-dir' to correspond
to ~/.guix-profile/lib/aspell rather than $prefix/lib/aspell-X.Y.

This is not strictly necessary for the 'aspell' program itself since
one can simply set "ASPELL_CONF=dict-dir $HOME/.guix-profile/lib/aspell".
However it is necessary for applications that use libaspell since
'ASPELL_CONF' is not honored in this case.  See <https://bugs.gnu.org/25836>.
