ld.so.8: Remove discussion of environment variables understood by libc5 

libc5 disappeared long ago, so cease cluttering up this page
with those ancient details. Thus, remove discussion of the
following environment variables: LD_AOUT_LIBRARY_PATH,
LD_AOUT_PRELOAD, LD_KEEPDIR, LD_NOWARN, and LDD_ARGV0.
