[package] update openvpn-devel to week 45 snapshot

the following patch brings openvpn-devel up to "week 45" (most recent)
openvpn-devel version from git, which has one important bugfix
("route" command with special-case targets was broken) and enables
parallel building.

Also, it seems that "--enable-small" was lost in the application of
the last commit - or my local SVN is confused.  I know I sent this last
time, but "svn diff" claims it's not in the repository right now...

Anyway, here's the output of "svn update ; svn diff" on the packages feed
tree...
