Allow additional map permission when reading hwdb
I'm seeing a denial for udev to map /etc/udev/hwdb.bin.
This creates and uses a new interface to allow the needed
permission for udev.
type=AVC msg=audit(1551886176.948:642): avc: denied { map } for pid=5187
comm="systemd-udevd" path="/etc/udev/hwdb.bin" dev="dm-1" ino=6509618
scontext=system_u:system_r:udev_t:s0-s0:c0.c1023
tcontext=system_u:object_r:systemd_hwdb_t:s0 tclass=file permissive=1
Updated from previous to create a new interface.
