OK, seems to be the easiest way. Originally, I wanted to avoid it
because idk what is the correct way. I've created a simple script to do
it:
[snip]
The script is not good because it doesn't touch only OS/2 table but it
regenerates the whole font file (different GPOS, dropping DSIG and
without fmflags also dropping KERN table).
I've also tried to use ttx with a hope that it won't touch other tables,
but it crashed on parsing OpenSans font.
Considering changing fsType is just a change to 16 bits + a 32-bit
checksum, it shouldn't be necessary to regenerate the entire font. In
fact, Tom7 created a program to do just this job many years ago, called
"embed":

I've just improved this to recalculate the OS/2 table checksum correctly
and handle multiple fonts in one go:

If you'd like to package this as well, you could use it in your Open Sans
package and you'd have something else to show sponsors :-)
This solution is much nicer and can be used by other font packages as well.
Here's the new package: https://bugzilla.redhat.com/show_bug.cgi?id=1036754
