v2.26.7: fix health check SDR detection on macOS (#188)

Browse Source 
timeout (GNU coreutils) is not available on macOS, causing rtl_test to
silently fail and report no SDR device found. Now tries timeout, then
gtimeout (Homebrew coreutils), then falls back to background process
with manual kill.
