Fix gdbserver's regcache_raw_read_unsigned on big endian hosts

The regcache_raw_read_unsigned function is memcpy'ing a 32-bit value
directly into a 64-bit variable, which doesn't work on big endian
targets.

Fix this by memcpy'ing to a buffer, and then using
extract_unsigned_integer, just like gdb's version.
