fix(filetype.lua): always return a string in getline helper function (#17852)

Uses of `getline` in `filetype.lua` currently assume it always returns a
string. However, if the buffer is unloaded when filetype detection runs,
`getline` returns `nil`. Fixing this prevents errors when filetype
detection is run on unloaded buffers.
