Allow using expanded macro without loading feature

In the macro `use-package-with-elapased-timer' use `bound-and-true-p'
go get the values of the customizable options `use-package-verbose'
and `use-package-minimum-reported-time'.  This way the library only
has to be required at compile time, provided these options are not
actually customized.  If the user has changed the values, then she
also has to load the library at runtime or the macros fall back to
the default of doing their job silently.  See https://github.com/jwiegley/use-package/issues/149.
