bug#12485: 24.2; Running top in eshell shows error

[Glenn Morris]

Version: 24.3

I changed eshell-term-name to default to term-term-name (= eterm-color).
This means it will pick up the supplied etc/e/eterm-color entry and not
need a system terminfo entry. It was probably an oversight that
eshell-term-name was not changed back when etc/e/eterm was renamed to
etc/e/eterm-color.
