Fix package export for Servlet 3.1 specification

For historical reasons (bug 360245), the exported by
FrameworkLauncher#generateExtensionBundle package version of
"javax.servlet.*" for Servlet 3.1 specification is 2.7. With the recent
changes in "org.eclipse.equinox.http.servlet" MANIFEST.MF, the required
"javax.servlet.*" package version is 3.1 (same as servlet spec).

Change FrameworkLauncher#generateExtensionBundle to export
"javax.servlet.*" for Servlet 3.1 as both 2.7 and 3.1.

Bug 545682: org.eclipse.equinox.http.servlet and
org.eclipse.equinox.servletbridge do not work together anymore in Tomcat
8.5.x
