[debug] Allow debug colourisation to be disabled
Some BIOS console redirection capabilities do not work well with the
colourised debug messages used by iPXE. We already allow the range of
colours to be controlled via the DBGCOL=... build parameter. Extend
this syntax to allow DBGCOL=0 to be used to mean "disable colours".
