[reltool] Add test cases for handling of escripts

OTP-9794
OTP-9968

The following test cases are added:
* create_standalone_beam
* create_standalone_app
* create_multiple_standalone
* load_config_escript_path
* load_config_same_escript_source
* load_config_same_escript_beam
* load_config_add_escript

Most of them are temporarily skipped since they re-produce known
problems that will be corrected in a later commit.
