feat: vmtest.sh: the boot loader test for every loader the ISO advertises

Browse Source 
One VM per loader, Steam Machine (--fremont): Steamify's state as its menu sees it,
OS name untouched, loader identity, the DKMS modules for every kernel, Steamify's
loader-specific code (hdmi_remove_boot_param), a kernel update, and a reboot into
each of the two kernels. Headless by default with a log Konsole (--window shows
the VMs). Fails when an advertised loader has no test. Limine 41, systemd-boot 40,
GRUB 40 checks pass.

# Guest side: Steamify's boot-loader-specific code, hdmi_remove_boot_param
# (older versions put drm.edid_firmware= on the kernel command line): seed
# the parameter where this loader keeps it, run the removal, and check that
# it's gone and the boot entries are rebuilt.
