Configure correct app dir when building /_error fallback in dev

[eps1lon]

Error is still catastrophic in case a custom .babelrc is used.

Instead of

[TypeError: The "path" argument must be of type string. Received undefined] {
  code: 'ERR_INVALID_ARG_TYPE'
}

we now get

[Error: ENOENT: no such file or directory, open '/private/var/folders/pw/l2r2l0mn4gq7jg3bprfv_w740000gn/T/next-install-68e307a0ecd55c8dbe2f950c2e51318949c2c0f04369b26b867482de73d50e44/.next/fallback-build-manifest.json'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '/private/var/folders/pw/l2r2l0mn4gq7jg3bprfv_w740000gn/T/next-install-68e307a0ecd55c8dbe2f950c2e51318949c2c0f04369b26b867482de73d50e44/.next/fallback-build-manifest.json'
}

But this was a clear oversight so we should land it regardless.
