ustream-ssl: correct year in PKG_VERSION string

ustream-ssl: correct the year in the PKG_VERSION string, as both r45157 and
r45441 left the old year 2014 there. For a casual user it may seem that the
current code is from April 2014, although
a4ca61527236e89eb9efb782fd9bfd04796144e3 is from April 2015.
