find command, fix -Wpoint-sign 

From: Pedro Alves <palves@redhat.com>

The find command's patter/buffer that is passed to the target is a
binary blob, not a string.

$ make WERROR_CFLAGS="-Wpointer-sign -Werror" findcmd.o -k 2>&1 1>/dev/null
../../src/gdb/findcmd.c: In function ‘find_command’:
../../src/gdb/findcmd.c:278:6: error: pointer targets in passing argument 3 of ‘target_search_memory’ differ in signedness [-Werror=pointer-sign]
In file included from ../../src/gdb/findcmd.c:26:0:
../../src/gdb/target.h:1582:12: note: expected ‘const gdb_byte *’ but argument is of type ‘char *’

	* findcmd.c (put_bits): Change type of parameter to 'gdb_byte *'.
	(parse_find_args, find_command): Change type of pattern buffer
	locals to 'gdb_byte *'.
