[PATCH] [SRU Xenial/Yakkety/Zesty] [Artful] [unstable] UBUNTU: [Packaging] exact extend-diff-ignore matches

[Thadeu Lima de Souza Cascardo]

BugLink: http://bugs.launchpad.net/bugs/1693504

gen-auto-reconstruct script adds extend-diff-ignore options to
debian/source/options for symlinks not found in the orig tarball.

These options, however, are regular expressions, and match any part of a
file path. This may cause some files to be excluded from source when
they are not an exact match, but are a partial match to those symlinks.

Using beggining and end of string metacharacters fix the issue.

This problem was found in one of the derivatives, which contained a
symlink, whose name was a prefix for a directory in the same path,
leading that entire directory to be excluded from source.
