test: skip failing watch file tests on freebsd (#26110)

Quick fix as follow up to https://github.com/neovim/neovim/pull/26108

kqueue only reports events on a watched folder itself, not for files
created or deleted within. So the approach the PR took doesn't work on FreeBSD.

We'll either need to bring back polling for it, combine watching with manual
file tracking, or disable LSP file watching on FreeBSD
