spec: fix <liburing/*.h> permissions
spec: fix <liburing/*.h> permissions

There are two issues with the <liburing/*.h> headers:
1. They are installed with 0755 permissions.
2. The empty /usr/include/liburing/ directory is left behind by rpm -e.

Fix this by specifying the directory (not just globbing the files inside
it) and letting rpm use the default permissions on these files.
