Subject: [PATCH] flasher: switch extlinux.conf for soysauce on Windows and
 macOS

The Linux flash script swaps extlinux.conf.soysauce into extlinux.conf for
the soysauce variant (it boots with an explicit FDT), but the Windows
PowerShell writer and the macOS script only copied the DTBO and wrote the
variant file. On those platforms a soysauce card kept the default
extlinux.conf, ignored extlinux.conf.soysauce, and the console never booted.

Add the same swap (back up extlinux.conf, copy extlinux.conf.soysauce over
it) to both the Windows and macOS post-write config steps.
