perf tools: Provide subcmd configuration at runtime
Create init functions for exec_cmd.c and pager.c. This allows their
configuration to be specified at runtime so they can be split out into a
separate library which can be used by other programs. Their
configuration is stored in a shared subcmd_config struct.
