[ng] texi: remove some crufty code to support obsolete environment

* lib/am/texi-vers.am (%STAMPVTI%): We don't really care anymore about
older systems whose 'mv' program can't move across file systems, nor do
we care about past problems of GNU mv in the AmigaDOS environment.  So
simplify the code accordingly.
