libutils: add %pUl format for UUIDs

The debug traces in tee_ta_manager.c do not show the last 8 bytes of
the TA UUIDs, which makes the output confusing sometimes.
This commit adds support for a new printf format for little-endian
encoded UUIDs: %pUl, and uses it in tee_ta_manager.c. For example:

TEE_UUID uuid;
DMSG("UUID: %pUl", (void *)&uuid);

...will print something like:

[...] UUID: cb3e5ba0-adf1-11e0-998b0002a5d5c51b

The new format is available when using the trace macros or the new
functions: snprintk(), vsnprintk() declared in <printk.h>.
But, snprintf() and vsnprintf() are not modified in order not to break
standard compliance.

This format is taken from the Linux kernel [1].

debug: enable bget memory leak detection

This patch enables memory leak detection in bget_malloc.c.
This is very helpful to find memory leakage issue in teecore
or user TA. To enable it in teecore, build optee_os with
`CFG_TEE_CORE_MALLOC_DEBUG=y`. For user TA, build optee_os
with `CFG_TEE_TA_MALLOC_DEBUG=y`.

Then, add the following statement at some point of your
code that might frequently been triggered:

mdbg_check(1);

It will dump allocated memory blocks and the holders of
them. If you find a memory block appears multiple times
after the system runs a period of time, it is very likely
the source of memory leakage.

Here is an example output:

ERR TEE-CORE:mdbg_check:720: Orphaned buffer: 0 bytes core/tee/tee_svc_storage.c:260

You can see the buffer hold by strdup.c:34 appears 4 times,
so it's very likely to be the source of memory leakage.
