* Use user-preferred locale
Previous fix adding `L` format specifier was correct but only fixed half
of the problem, as C++ locale is set up to be "C" by default. GTK client
used to call `setlocale(LC_ALL, "")` to set up user-preferred locale
which only affected C functions and `std::locale` (used by libfmt) was
unaware of those changes.
Apply the fix to all the binaries since they're all doing some sort of
output to the user and calling libtransmission helpers, as well as using
libfmt directly.
* Improve libtransmission's json-test
Set the locale C++ way to avoid any sort of inconsistencies, and also
restore it to the old one once finished testing.
* Improve transmission-show test runner script
Quote outputs to avoid CMake error about `message()` being called with
no arguments. Capture stderr to the same output file. Fallback to `git
diff` if `diff` wasn't found. A few other minor changes.

ABOUT TRANSMISSION-QT
Transmission-qt is a GUI for Transmission loosely based on the GTK+ client.
This is the only Transmission client that can act as its own self-contained
session (as the GTK+ and Mac clients do), and can also connect to a remote
session (as the web client and transmission-remote terminal client do).
Use Case 1: If you like to run BitTorrent for awhile from your desktop,
then the Mac, GTK+, and Qt clients are a good match.
Use Case 2: If you like to leave BitTorrent running nonstop on your
computer or router, and want to control it from your desktop or
from a remote site, then transmission-remote and the web and Qt clients
are a good match.
To use the Qt client as a remote, in the menu go to Edit > Change Session
The Qt client is also the most likely to wind up running on Windows,
though that's not a high priority at the moment...
