compositor-fbdev: Instead of less than 1 Hz use default refresh rate
I ran Weston on a Nexus 4 mobile phone, with a native GNU/Linux userland,
and the latest Android kernel for that device from LineageOS [1].
calculate_refresh_rate() returned 1 (mHz), which gets rounded to 0 Hz later
and results in nothing being drawn to the screen.
This patch makes sure, that there is at least a refresh rate of 1 Hz, because
it returns the default refresh rate of 60 Hz otherwise.
