pinentry 0.9.6 changed the `qt4` flag to just `qt`. Additionally,
the `--with-x` option has not been there for a while. This commit
renames and removes the flags, respectively.
The pinentry_gnome package requires gcr. Unfortunately, when configure
asks about the library (or `pkg-config --libs gcr-base-3` is used) it
fails because glib is not in scope.
```
$ pkg-config --libs gcr-base-3
Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'glib-2.0', required by 'gcr-base-3', not found
```
This commit moves glib and gtk to `propagatedBuildInputs` so pkgconfig
could find them.

Apparently gwrap will not compile with guile-2.2 [1], even though the
news for version 1.9.15 says it "allows" Guile 2.2 [2]:
> it will _not_ compile using 2.2
Furthermore, it seems like it isn't being developed anymore either [1]:
> Also note that g-wrap itself is not being further developed anymore,
> it is recommended for new projects to use Guile's dynamic FFI.
Also, guile-gnome-2.16.5 is apparently compatible with guile-2.2 [3],
but I'm not sure how they built it with guile-2.2 because gwrap 1.9.15
(latest release) apparently doesn't build with guile-2.2. (And certainly
when I try to build gwrap 1.9.15 with guile-2.2 it doesn't work. Maybe
it can be made to work with certain compile flags, but I haven't pursued
that further due to [1] anyway.) This is why guile-gnome is still on
2.16.4 here. Because, although 2.16.5 can still (apparently) build with
guile-2.0.14, guile_2_0 is only at guile-2.0.13.
So to update guile-gnome to 2.16.5, guile_2_0 would first have to be
updated to 2.0.14.
