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.

	* linux-low.h (struct linux_target_ops): Remove the ops.
	(class linux_process_target) <supports_fast_tracepoints>
	<install_fast_tracepoint_jump_pad>
	<get_min_fast_tracepoint_insn_len>: Remove.
	* linux-low.cc (linux_process_target::supports_fast_tracepoints)
	(linux_process_target::install_fast_tracepoint_jump_pad)
	(linux_process_target::get_min_fast_tracepoint_insn_len): Remove.
	* linux-x86-low.cc (class x86_target) <supports_fast_tracepoints>
	<install_fast_tracepoint_jump_pad>
