vfs_vector: Make creation of array vfs files less verbose 

We can add a helper function to make creation of these files nicer.
While we're at it, we can eliminate an unnecessary std::array copy in
the constructor. This makes the overhead on some of these functions way
less intensive, given some arrays were quite large.

e.g. The timezone location names are 9633 bytes in size.
