net-libs/gsoap: compatibility patch for LibreSSL

This patch fixes building with dev-libs/libressl-2.6.4.  This patch will
not be needed once dev-libs/libressl-2.7.x goes stable.  Additionally,
fix slot/subslot modifier to ensure rebuilds are trigged for API
changes.

Closes: https://bugs.gentoo.org/617264
Package-Manager: Portage-2.3.31, Repoman-2.3.9
