Leak reported via Natanael Copa on IRC when used by libvirt:
==623== 5,677,056 bytes in 693 blocks are definitely lost in loss record 3,354
of 3,358

Even without symbols, the lone call to vasprintf in drv_debian was
a pretty blatant leak.
* src/drv_debian.c (interface_deps): Free path when done with it.
