filesystem: Rename a variable named "append" that is actually prepending.

Browse Source 
(Strictly speaking, this was probably meant to be an "append" to the home/base
directory before the org/app name are appended to _that_, but it's definitely
added to the absolute start of the string on Emscripten, so might as well make
all of these match.

Reference PR #15262.
