Avoid usage of github.com/mtrmac/gpgme

[MovieStoreGuy]

Describe the bug
Trying to compile the otel collector contrib on MacOs fails within missing definitions. Furthermore, depends on cgo and limits ability to create a static binary that can be shipped anywhere.

Steps to reproduce
On an MacOS machine / Windows run make test

What did you expect to see?
make test works without issue.

What did you see instead?

/Users/smarciniak/go/pkg/mod/github.com/mtrmac/[email protected]/data.go:4:11: fatal error: 'gpgme.h' file not found
 #include <gpgme.h>
          ^~~~~~~~~

What version did you use?
Version: main @ 0d78df6

Environment
OS: MacOs 11.6
Compiler(if manually compiled): go 1.17.0

This comes from the Podman receiver.

Also, make test is missing CGO_ENABLED=0 on its task definition. @MovieStoreGuy could you try and see if adding CGO_ENABLED=0 to make test fixes this for you?

Collector itself excludes these dependencies when building as they are not actually needed for the podman receiver.

You can do the same by using the following build tags:

containers_image_openpgp,exclude_graphdriver_btrfs,exclude_graphdriver_devicemapper

@mx-psi I actually had issues also running make golint and suspected it to be the same issue but present in a different way.
