[PATCH 1/2] covoar: Store only the file name in ExecutableInfo

[Alex White]

This changes the ExecutableInfo class to only store the executable
file's name rather than an entire instance of rld::files::object. This
allows the rld::files::object to be cleaned up in the ExecutableInfo
constructor.

Updates #4383
