Commit e6d2c436ff ("tools/mm: allow users to provide additional
cflags/ldflags") passes now CFLAGS to Makefile. With this, build systems
with default -Werror enabled found:
slabinfo.c:1300:25: error: ignoring return value of 'chdir'
declared with attribute 'warn_unused_result' [-Werror=unused-result]
chdir("..");
^~~~~~~~~~~
page-types.c:397:35: error: format '%lu' expects argument of type
'long unsigned int', but argument 2 has type 'uint64_t'
{aka 'long long unsigned int'} [-Werror=format=]
printf("%lu\t", mapcnt0);
~~^ ~~~~~~~
..
Fix page-types by using PRIu64 for uint64_t prints and check in slabinfo
for return code on chdir("..").

This flag has similar constraints to PG_owner_priv_1 -- it is ignored by
core code, and is entirely for the use of the code which allocated the
folio. Since the pagecache does not use it, individual filesystems can
use it. The bufferhead code does use it, so filesystems which use the
buffer cache must not use it for another purpose.

With SLOB removed we no longer need the PG_slob_free alias for
PG_private. Also update tools/mm/page-types.

Rename tools/vm to tools/mm for being more consistent with the code and
documentation directories, and won't be confused with virtual machines.
