FS-10091: [mod_conference] Conference play file with full-screen=true has side effect on member video #resolve

modcheck.sh gets called by build/Makefile when doing "make install" with
parameter "$(modulesdir)". This is fine when the install is done on a
live system. But when "make install" was called with a "$DESTDIR" then
this won't work, as the correct path would then be
"$(DESTDIR)$(modulesdir)". So add "$(DESTDIR)" in front.

Currently gentls_cert uses "@prefix@/conf/ssl". But FreeSWITCH's
configure script provides "@certsdir@", so let's use that instead.
