lrzsz: fix random build failures by really disabling autofoo

Currently we're seeing random build failures, caused by autofoo being
called on very ancient bundled autofoo:

  cd . && aclocal
  aclocal.real: warning: autoconf input should be named 'configure.ac', not 'configure.in'
  acinclude.m4:2: warning: underquoted definition of AC_REPLACE_GNU_GETOPT
  acinclude.m4:2:   run info Automake 'Extending aclocal'
  acinclude.m4:2:   or see https://www.gnu.org/software/automake/manual/automake.html#Extending-aclocal
  configure.in:106: error: automatic de-ANSI-fication support has been removed

For some reason that `touch` based neutralization introduced in commit
6d6c4b2 ("lrzsz: update to v0.12.21rc and fix a CVE") doesn't
always work.

So lets fix it by removing the autofoo bits from the bundled Makefile.in
and while at it remove processing of man and testsuite subdirs to save
some computing cycles.

Fixes: #25543
