install and enable eBPF Plugin by default (#8665)

* netdata_installer_kernels: New kernels

This commit brings new kernels for our netdata-installer

* RH detection

This commit brings the RH detection to netdata-installer, but it cannot be
tested yet until we merge  a PR on kernel-collector

* netdata_installer_kernels: RH kernels

This commit brings updates that allows to install and run the collectors
on RH

* netdata_installer_kernels: Kernel variables

This commit brings definitions instead magic number to the isntaller

* netdata_installer_kernels: remove echo

This commit removes echo to avoid new line

* netdata_installer_kernels: Move C code

This commit removes the C code that will be inserted in another PR

* Update eBPF install to use released version.

This updates the install code for the eBPF plugin to properly utilize
(and verify) a tagged release of the plugin instead of pulling the
upstream master branch.

It also adds support for using a local copy of the tarball, and switchs
the default behavior to install the eBPF plugin instead of not
installing it.

* Tidy-up messages relating to eBPF.

* Fix typos in error handling functions.

* ebpf-release: New kernels

This commit brings the kernels necessary to support Debian 10.0

* ebpf-release: Bring support for new package format

* ebpf-release: collector as loader

This commit brings the necessary changes for the collector loads all
the nfiles depending of the kernel it is running

* Bump eBPF kernel-collector to v0.1.0

* Update --help to state eBPF is enabled by default and add --disable-ebpf option in --help output

* Remove deprecated kernel version compatibility checks

* Fix EBPF_TARBALL

* Remove libc path detection logic (deprecated0

* Use the new package structure of kernel-collector

* Relax the glob on netdata_ebpf as we may develop/distirbute other types of ebpf programs

* Fix ownership of ebpf libraries/programs

* Make the check-kernel-config.sh local to the installer

* Make plugins.ebpf = yes (by default)
