[PATCH] meta/conf/bitbake.conf: add default value for SRCREV

[Henning Schild <henning.schild@siemens.com>]

The line is taken from the bitbake.conf of OE. The value "INVALID" is
magic and makes bitbake throw exceptions in case the variable needs a
value assigned but a recipe did not assign one.
So it is a minor fix to improve error reporting when recipes have
mistakes.
