[PATCH] gdb: Fix false match issue in skip_prologue_using_linetable

[WANG Rui]

We should exclude matches to the ending PC to prevent false matches with the
next function, as prologue_end is located at the end PC.

  <fun1>:
    0x00: ... <-- start_pc
    0x04: ...
    0x08: ... <-- breakpoint
    0x0c: ret
  <fun2>:
    0x10: ret <-- end_pc | prologue_end of fun2
