autotools: Remove special handling for autoconf* and automake*
For reasons that are now shrouded in obscurity, autotools.bbclass
has long contained a special heuristic to avoid attempting to run
autoreconf when building autoconf or automake themselves. However,
the wildcard test against PN which is used there is problematic when
trying to build another package whose name happens to start with
"autoconf", and in any case it is silly to do this test at runtime
for every package. The individual recipes for autoconf and automake
can just as easily suppress the behaviour that they don't want by
providing a custom do_configure() method which just runs configure.
