Subject: [PATCH] zypperpkg: filter patterns that start with dot (#244)

For versions <=SLE12SP4 some patterns can contain alias, and can appear
duplicated.  The alias start with ".", so they can be filtered.

If the module try to search by the alias name (pattern:.basename, for
example), zypper will not be able to find it and the operation will
fail.

This patch detect and filter the alias, and remove duplicates.

Fix bsc#1171906

(cherry picked from commit d043db63000df2892b2e7259f580ede81e33724d)
