New install on fedora 30 links to stale file

[miguelraz]

I tried following the simple install steps described here

$ git clone --recursive https://github.com/wsmoses/Tapir-Meta.git
$ cd Tapir-Meta/
$ ./build.sh release
$ source ./setup-env.sh

but ended up getting an error because there is no file called /sys/ustat.h. I applied this patch and this one and the install worked as expected.
