In the UEFI context GUIDs are expected to be rendered in upper case.
The patch uses the formerly unused bit 1 of the parameter str_format of function uuid_bin_to_str() to indicate if we need upper or lower case output.
Function uuid_string() in vsprint.c is adjusted to correctly set the bit depending on the print format code.

Up to this point only a diagnostic message in mount_ubifs() using '%pUB' is concerned by the change. Further patches are needed to adjust the UEFI subsystem.
A unit test is provided inside the ut_print command.
