gio/tests/{meson.build,pollable.c}: Determine libutil SONAME at build time
Calling dlopen()
with libutil.so
makes the installed tests depend on
having glibc's development files installed. To avoid this, we can work
out the runtime library name at build time and dlopen
that instead.
This approach is taken from libfprint, thanks to Marco Trevisan.
(yes, it would be best if meson supported this directly)
