service: Resolve trivially avoidable copies (#5237)

Browse Source 
* am/am: Avoid redundant copy in GetProgramInfoFromCia()

We can just use a reference to the title metadata. Avoids copying
several data entries and std::vector instances that don't need to be
copied.

* hle/service: Avoid redundant copying of std::string

GetUserPath() returns the path as a reference, so we can make use of
said reference to avoid making copies.
