Cleanup unused easyblocks

[branfosj]

In #3089 we've cleaned up unused easyblocks instead of converting the run_cmd / run_cmd_qa use to run_shell_cmd. There is a list of easyblocks that do not use run_cmd / run_cmd_qa, this is the ones that are unused and remove them.

Need to check for indirect use of these (via EB_XYZ)
