Subject: [PATCH] v2v: linux: canonicalize module path for arch detection
 (RHBZ#1690574)

Kernel modules can be also symlinks to files available outside the
"canonical" module directory; the "file" API, used by the
"file-architecture" API, return the actual type of a file (so symlinks,
block devices, etc), and thus "file-architecture" fails on symlinks.

To prevent this situation, canonicalize the path of the module picked
for architecture detection: this way, "file-architecture" will act on a
real file.

(cherry picked from commit 0a093035d485b3c2e66d56541ebe159f1b632ba6)
