selinux: update numeric format specifiers for ebitmaps

Browse Source 
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.
