Libdpkg has some breaking changes in newer versions which prevented
compiling the deb_packages table on Ubuntu 15.04. This change looks for
the libpkg version user pkg-config and adds some preprocessor magic to
support the newer versions.
1. added docs for vagrant-aws support in Vagrantfile
2. removed aws target that have local vagrant support. inline-string'd aws.user_data
3. support building rhel6/7 in aws
4. correct aws-rhel6.6 name. it should be rhel6.5
I used CPack to generate deb package files from the CMake "install"
target. What this means is, whatever would get installed my "make
install" will get installed by the deb.
"make package" on ubuntu will generate a file named: `osquery-$VERSION-$DISTRO.$ARCH.deb`
Consider the following example:
```
root@vagrant-ubuntu-trusty-64:/vagrant/build# dpkg --info osquery-0.0.1-trusty.amd64.deb
new debian package, version 2.0.
size 11311330 bytes: control archive=350 bytes.
207 bytes, 9 lines control
