uprobes/core: Remove uprobe_opcode_sz
uprobe_opcode_sz refers to the smallest instruction size for that architecture. UPROBES_BKPT_INSN_SIZE refers to the size of the breakpoint instruction for that architecture. For now we are assuming that both uprobe_opcode_sz and UPROBES_BKPT_INSN_SIZE are the same for all archs and hence removing uprobe_opcode_sz in favour of UPROBES_BKPT_INSN_SIZE. However if we have to support architectures where the smallest instruction size is different from the size of breakpoint instruction, we may have to re-introduce uprobe_opcode_sz.
