Fix prerequisites of memcached build

The memcached "GET" script assumed sasl is available and was discovered
by "configure", and then disables it with a patch. If Sasl was not
available the patch would fail. Change this to use "sed", which deletes
the sasl lines regardless of whether it was found or not.

Also added mention in README that libevent is needed.

Introduce module with netperf server

Based on scripts inside osv.git/tools/netperf

One difference is that the install script does not invoke `sudo make
install`, instead it copies the netperf client to

  upstream/netperf-2.6.0/bin/netperf
add mruby module

Add mruby as an app.
When you want to add extensions(called mrbgems) on mruby, you'll need to specify git URI on build_config.rb, so this patch already includes some external mrbgems which tested on OSv.
Default cmdline argument will executes EShell, which is very simple shell for OSv/mruby environment.

Fix "haproxy" module

I don't know how this module ever worked - its modules.json entry was
broken, and the Makefile didn't have the proper dependencies...

Now it works.

Add "openjdk8" module

Currently, this module fetches OpenJDK's up-to-date sources, and compiles
them, when you do "cd apps/openjdk8; ./GET". This process is *very slow*,
and requires a bunch of unusual development libraries to be installed
(various X-Windows and sound libraries), so if you plan to try this, plan
to spend a lot of time on this compilation.

Now "make image=openjdk8" creates an image with Java 8.

Note, however, that module dependencies are still not done right - if you
do "make image=openjdk8,mgmt.shell", the mgmt module will not know that
openjdk8 is enough, and will bring *also* the "java" module (openjdk7).
This will be fixed in a later patch.

openjdk8: provide "java"

Say that openjdk8 provides "java", so that other modules that need java
will be satisfied with the openjdk8 module instead.
