Fails to deploy static files when using ternary operator

[styfle]

Hello again 👋

I had a problem deploying to Now 2.0 and I believe the root cause is in ncc and the way files are bundled together in the @now/node builder.

I was originally using a ternary operator to decide which file to dynamically read from the filesystem, but this always gave me the ENOENT: no such file or directory after deploying even though it worked fine on my machine.

After reading #216 I decided to see if changing the code would solve the problem and it worked! See the commit below for the fix.

This seems like it would be easy for users (like myself) to hit this bug and just give up. So it would be wonderful if this type of dynamic file reading could work with Now 2.0 😄

(forgive me if this is a duplicate bug)
