include/types.h: Provide linux-specific errno.h error codes
Although we have our own error codes, we occasionally import linux
sources which use the <errno.h> codes as return values. From a
maintenance standpoint it makes more sense to add such sources with
minimal modifications., even if it means not using coreboot error
codes. I'm also beginning to question the decision to provide
subsystem-specific error codes in a generic file, but that issue will
be addressed later, if needed.
