bitbake.conf: require conf/multiconfig/${BB_CURRENT_MC}.conf

Presently there is no check to verify the existence of configuration
files as listed in BBMULTICONFIG.
For example, BBMULTICONFIG = "foobar" in local.conf does not trigger
an error or even a warning when there is no conf/multiconfig/foobar.conf.
The missing file is silently ignored.

This patch changes the inclusion of all multiconfig configuration files as
a non-optional requirement. If the file is missing, we get an error such as:

ERROR: ParseError at /data/master-multi/poky/meta/conf/bitbake.conf:704: Could not include required file conf/multiconfig/foobar.conf

Although the "default" configuration is not listed in BBMULTICONFIG,
this change also requires the file multiconfig/default.conf to exist.
The "default" (non-multiconfig) configuration is normally configured via local.conf,
so although this file is required, it can/should be empty. This patch creates
an empty file default.conf in meta/conf/multiconfig.
