bcachefs: Fix format specifiers in bch2_btree_key_cache_to_text()
When building for a 32-bit target, for which 'size_t' is 'unsigned int',
there are two warnings around mismatched format specifiers and argument
types:

cc1: all warnings being treated as error
Use the proper 'size_t' specifier, '%zu', to clear up the warnings for
these platforms.
