Wladislav Wiebe 9523a02689 tools/mm: -Werror fixes in page-types/slabinfo
commit ece5897e5a10fcd56a317e32f2dc7219f366a5a8 upstream.

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("..").
