seq_file: Mark binary printing functions with __printf() attribute

Binary printing functions are using printf() type of format, and compiler
is not happy about them as is:

fs/seq_file.c:418:35: error: function ‘seq_bprintf’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]

Fix the compilation errors by adding __printf() attribute.
