spec: Fedora RPM cleanups

Cole Robinson and Fabio Valenti made a number of suggestions for the
.spec file:
https://bugzilla.redhat.com/show_bug.cgi?id=1766157

 * Release should be Release: 1%{?dist} so the .fcXX bits get appended
   to the version string
 * Source: should be a pointer to the upstream URL that hosts the
   release. In this case I think it should be
   https://github.com/axboe/liburing/archive/...
   the ending weirdness is due to github renaming the archive strangely.
   You might need to pass '-n %{name}-%{name}-%{version}' to
   %setup/%autosetup to tell it what the extracted archive name is
 * The %defattr lines should be removed:
   https://pagure.io/packaging-committee/issue/77
 * The Group: lines should be removed
 * All the BuildRoot and RPM_BUILD_ROOT lines should be removed. %clean
   should be removed
 * The ./configure line should be replaced with just %configure
 * The 'make' call should be %make_build
 * The 'make install' call should be %make_install
 * The %pre and %post sections can be entirely removed, ldconfig is
   done automatically:
   https://fedoraproject.org/wiki/Changes/Removing_ldconfig_scriptlets
 * The devel package 'Requires: liburing' should instead be: Requires:
   %{name} = %{version}-%{release}
 * The devel package should also have Requires: pkgconfig
 * I think all the %attr usage can be entirely removed, unless they are
   doing something that the build system isn't doing.
 * The Provides: liburing.so.1 shouldn't be necessary, I'm pretty sure
   RPM automatically adds annotations like this
 * Replace %setup with %autosetup, which will automatically apply any
   listed Patch: in the spec if anything is backported in the future.
   It's a small maintenace optimization

These changes work on Fedora 31 and openSUSE Leap 15.1.  Therefore they
are likely to work on other rpm-based distributions too.
