Subject: [PATCH] basic: drop unnecessary strempty() call in replace_env

strempty() converts a NULL value to empty string, so
that it can be passed on to functions that don't support NULL.

replace_env calls strempty before passing its value on to strappend.

strappend supports NULL just fine, though, so this commit drops the
strempty call.
