Use the correct, according to Documentation/core-api/printk-formats.rst,
format specifiers for numeric arguments in string formatting.
The general bit type is u32 thus use %u, EBITMAP_SIZE is a constant
computed via sizeof() thus use %zu.

Fixes: 0142c56682fb ("selinux: reject invalid ebitmaps")
Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
Closes: https://lore.kernel.org/linux-next/20240327131044.2c629921@canb.auug.org.au/

Looks good, thanks.  Merged into selinux/dev.
