Subject: [PATCH] build(uninstall): don't build if installation manifest not
 found

Due to the way neovim project is set up, running `make uninstall` would
previously build neovim in order to determine whether neovim was
installed. Instead, check if installation manifest file exists and if
not then skip building entirely.
