Make default search paths available as util fn

It's the removed section from the get_config() function, but with an
extra Vec<_> creation. This is necessary here because the strings from
the environment variable don't live long enough for lazy evaluation.

-Subject: Lift the empty-body string outside the let-if
-
-The if-else block that selects between the body of the Release or a
-placeholder is returning references to variables that only exist
-*inside* the body of the if-else blocks. Newer Rust versions seem to
-understand the intent and do The Right Thing anyway (or they have some
-other rule for how if-else block scopes work).
-
-Manually lifting the variable to an outer scope resolves the problem.
