gdbserver/linux-low: turn fast tracepoint ops into methods 

gdbserver/ChangeLog:
2020-04-02  Tankut Baris Aktemur  <tankut.baris.aktemur@intel.com>

	Remove the 'install_fast_tracepoint_jump_pad' and
	'get_min_fast_tracepoint_insn_len' linux target ops to let the
	concrete linux target define the ops by overriding the declarations
	of process_stratum_target.
