fix embed not working with -o

[nlepage]

Hi,

It seems that the embed impl won't work with the new -o option.

Here's a diff of the walk example showing the problem:

Here's what I did:

• Create a new package app/pkged with just a package.go
• "Blank import" it from main.go

Go run the example without running pkger works fine.

After running pkger -o pkged doesn't work anymore.

I'm not sure how to write a test for this... but the fix works for the walk example and hopefully for all the other cases.

Thank you for your work.
