Make pinentry::inquire_pin return String directly

The inquire_pin function of the pinentry module used to return a vector
of bytes, as that is what is ultimately read from the gpg-agent process.
All clients of this function, however, work with a string and, hence,
convert this vector into a string.
As it turns out, for better or worse, the pinentry::parse_pinentry_pin
function (which produces the result of inquire_pin) internally already
works with a string but then converts it back. That is both not useful
and a waste of resources.
This change adjusts both functions of interest to simply return a String
object instead, removing the need for conversions at the clients. While
at it, the patch also removes the need for a bunch of unnecessary
allocations caused by sub-par parameter type choice.
