Bug#795052: sleuthkit: Uses embedded copy of libexif-0.6.20

[Scott Kitterman]

Source: sleuthkit
Version: 4.1.3-11
Severity: normal

Although not a must in Debian policy, the preference is to not use embedded
copies of libraries.  sleuthkit-4.1.3/framework/modules/c_LibExifModule has
an embedded copy of libexif-0.6.20 that is used during package build.  It
would be better to use the system libexif.
