Loading packages into ghci doesn't set options.

[George Russell]

For example, with the attached test-package.conf file,
we see that -fglasgow-exts in the first case works (because the package is
loaded in the beginning), but in the second case it doesn't (because the
package is loaded during GHCi).

This also applies to -fallow-overlapping-instances and friends, it appears.
