package/matchbox-starup-monitor: fix build without C++

Browse Source 
matchbox-startup-monitor is an ageing package, and uses an old
configure.ac with archaic constructs. This had generated a configure
script that incorrectly tries to look for and validate a C++ compiler:

    checking for powerpc64le-buildroot-linux-gnu-g++... no
    checking whether we are using the GNU C++ compiler... no
    checking whether no accepts -g... no
    checking dependency style of no... none
    checking how to run the C++ preprocessor... /lib/cpp
    configure: error: C++ preprocessor "/lib/cpp" fails sanity check

Calling autoreconf fixes the issue, as the generated configure no longer
tries to look for a C++ compiler at all anymore. Running autoreconf does
not add any new dependency, as they are already in the dependency chain
via other packages.
