No preview on symlink

[octvs]

On my setup symlink previews on lf is not showing up with ctpv, although on
a shell ctpv outputs as expected.

ctpv a-symlink-leading-to-file # outputs symlink info text + pic preview
# Go in lf and check the same file
lf a-symlink-leading-to-file # only symlink info on right hand side

Placing set nosymlinkinfo to ctpv config resolves the issue, but it would be
ideal to also keep the symlink information.

Here are relevant configs

$XDG_CONFIG_HOME/lf/.lfrc

set previewer ctpv

&ctpv -s $id
&ctpvquit $id
set cleaner ctpvclear

$XDG_CONFIG_HOME/ctpv/config

set chafasixel
preview image image/* {{
	chafa -s "${w}x${h}" -f sixels --polite on "$f"
}}
set nosymlinkinfo

The preview image part is taken from #90
