Mike Fleetwood 9f473b70cb Always require C++11 compilation (!117)
All the oldest supported distributions now have versions of GTK C++
libraries which require C++11 compilation, therefore forcing GParted to
require C++11 compilation [1][2][3].  Fragment of existing ./configure
output which lists the library versions requiring C++11 compilation:

    $ ./configure
    ...
    checking for glibmm >= 2.45.40 which requires C++11 compilation... yes
    checking for libsigc++ >= 2.5.1 which requires C++11 compilation... yes
    checking for gtkmm >= 3.18.0 which requires C++11 compilation... yes
    checking whether g++ supports C++11 features with -std=gnu++11... yes

The oldest supported distributions and their versions of GTK C++
libraries and GCC compiler:

    Distribution        gtkmm    glibmm   libsigc++   gcc

    Debian 10           3.24.0   2.58.0   2.10.1      4.8.3
    RHEL / CentOS 7.9   3.22.2   2.56.0   2.10.0      4.8.5
    SLES 12 SP5         3.20.1   2.48.1   2.8.0       4.8
    Ubuntu 20.04 LTS    3.24.2   2.64.2   2.10.2      9.3.0

Technically GCC didn't have full C++11 support until GCC 4.8.1 [6] and
SLES 12 SP5 only has GCC 4.8 (as well as many later versions of GCC).
However which ever version of the GCC compiler is being used to compile
the GTK C++ libraries it must have all the features needed to compile
those libraries.

Simplify the configure script and just always require a C++11 capable
compiler.  This also allows the use of C++11 features in the GParted
code.
