Fix compilation warning in jemalloc's malloc_vsnprintf (#7789)

Browse Source 
Change `val` to `unsigned char` before being tested.
The fix is identical to the one that's been made in upstream jemalloc.

warning is:
src/malloc_io.c: In function ‘malloc_vsnprintf’:
src/malloc_io.c:369:2: warning: case label value exceeds maximum value for type
  369 |  case '?' | 0x80:      \
      |  ^~~~
src/malloc_io.c:581:5: note: in expansion of macro ‘GET_ARG_NUMERIC’
  581 |     GET_ARG_NUMERIC(val, 'p');
      |     ^~~~~~~~~~~~~~~
