gdbserver/linux-low: delete 'linux_target_ops' and 'the_low_target'

All the linux target ops have been moved into linux_process_target
as methods.  The 'linux_target_ops' struct and its instantiations
are now obsolete.  Delete them.

 	Remove the 'get_ipa_tdesc_idx' linux target op and let a concrete
 	linux target define the op by overriding the declaration in
 	process_stratum_target.
