[committed] Fix Wformat warnings in htab_report with CC="gcc -m32"

[Tom de Vries <tdevries@suse.de>]

Hi,

Using:
...
$ make CC="gcc -m32"
...
we run into this warning:
...
gcc -m32 -O2 -Wall -W -D_FILE_OFFSET_BITS=64 -DDWZ_VERSION='"0.13"' \
  -DFSF_YEARS='"1992-2019"' -DRH_YEARS='"2001-2018"' -DSUSE_YEARS='"2019"' \
  -c -o dwz.o /data/dwz/dwz.git/dwz.c
dwz.c: In function 'htab_report':
dwz.c:1256:37: warning: format '%lu' expects argument of type \
  'long unsigned int', but argument 3 has type 'size_t {aka unsigned int}' \
  [-Wformat=]
     fprintf (stderr, "      size: %lu\n", size);
                                   ~~^
                                   %u
...

Fix this and similar in htab_report by using %zu instead.

Committed to trunk.

Thanks,
- Tom
