Remove termcap entry reordering; install the file verbatim instead

termcap entry reordering requires ex (which is available via usr.bin/vi), which
breaks on build hosts where installworld is run with MK_VI == no (or when
make delete-old is run on ^/projects/building-blocks as vi, et al, are
removed on the branch when the knob is tweaked to => "no")

Reordering termcap was believed to improve performance, but the file is now
accessed via /etc/termcap.db, so /etc/termcap (and /usr/share/misc/termcap by
proxy) access is less preferred.

Reordering the file broke the historical comment <-> entry mapping as well,
which could muddle the purpose of entries in the file, so it could be
potentially harmful to readers in its reordered state.

Third, if you are not a super user and cannot create the directory
/usr/lib/tabset, make a corresponding directory somewhere you can and add
a line to reorder to globally change all /usr/lib/tabset's to your own
path name. This change is better than just changing the termcap.src file
path name. This change is better than just changing the termcap file
because it makes it easier to diff it from newer distributed versions.
Try to keep the source as is whenever possible, and put mungings into
reorder.
