binfmt_misc: use print_hex_dump_debug() for the register debug output

The hex dumps in create_entry() are compiled out unless someone edits
the file to define DEBUG while the pr_debug() calls right next to
them are dynamic-debug aware. Switch the dumps to
print_hex_dump_debug() which follows the same rules as pr_debug() so
the register parsing debug output is uniformly controlled through
dynamic debug, and remove the USE_DEBUG machinery.

Drop the magic[masked] dump instead of converting it: it printed the
bitwise AND of two buffers dumped right above it and required a
temporary allocation on every registration just to recompute what
the reader can derive from the magic and mask dumps directly.
