support/testing: add build tests for the syslinux bootloader

This commit adds four new tests for the syslinux bootloader:

 - Building on x86, for legacy BIOS
 - Building on x86, for EFI BIOS
 - Building on x86-64, for legacy BIOS
 - Building on x86-64, for EFI BIOS

Runtime testing in Qemu would certainly be possible, but is left as a
future addition to these tests.
