Introduce TESTSUITE_FLAGS

[Noah Misch]

I have patched my tests/Makefile.am as follows for the last few weeks, and I
suspect others may find it handy.  This lets me run

make check TESTSUITE_FLAGS="-k autotest"

instead of

make && cd tests && make testsuite && ./testsuite -k autotest

        * tests/Makefile.am (installcheck-local): Use $(bindir).
        (check-local, installcheck-local): Pass TESTSUITE_FLAGS.
        * doc/autoconf.texi (Making testsuite Scripts): Recommend the same
        Makefile.am scheme Autoconf now uses.
