perf trace beauty prctl: Default header_dir to cwd to work without parms

Useful when checking the effects of header synchs for the files it uses
as a input to generate string tables, in retrospect this is how it
should've been done from day 1, not requiring the header_dir to be set
on the Makefile, will change everything later, so that the only parm,
common to all generators will be $(srctree) and $(beauty_outdir).

So, to see what it generates, just call it without any parameters:

  $ tools/perf/trace/beauty/prctl_option.sh
  static const char *prctl_options[] = {
	  [1] = "SET_PDEATHSIG",
	  [2] = "GET_PDEATHSIG",
	  [3] = "GET_DUMPABLE",
	  [4] = "SET_DUMPABLE",
	  [5] = "GET_UNALIGN",
	  [6] = "SET_UNALIGN",
	  [7] = "GET_KEEPCAPS",
	  [8] = "SET_KEEPCAPS",
	  [9] = "GET_FPEMU",
	  [10] = "SET_FPEMU",
	  [11] = "GET_FPEXC",
	  [12] = "SET_FPEXC",
	  [13] = "GET_TIMING",
	  [14] = "SET_TIMING",
	  [15] = "SET_NAME",
	  [16] = "GET_NAME",
	  [19] = "GET_ENDIAN",
	  [20] = "SET_ENDIAN",
	  [21] = "GET_SECCOMP",
	  [22] = "SET_SECCOMP",
	  [25] = "GET_TSC",
	  [26] = "SET_TSC",
	  [27] = "GET_SECUREBITS",
	  [28] = "SET_SECUREBITS",
	  [29] = "SET_TIMERSLACK",
	  [30] = "GET_TIMERSLACK",
	  [35] = "SET_MM",
	  [36] = "SET_CHILD_SUBREAPER",
	  [37] = "GET_CHILD_SUBREAPER",
	  [38] = "SET_NO_NEW_PRIVS",
	  [39] = "GET_NO_NEW_PRIVS",
	  [40] = "GET_TID_ADDRESS",
	  [41] = "SET_THP_DISABLE",
	  [42] = "GET_THP_DISABLE",
	  [45] = "SET_FP_MODE",
	  [46] = "GET_FP_MODE",
  };
  static const char *prctl_set_mm_options[] = {
	  [1] = "START_CODE",
	  [2] = "END_CODE",
	  [3] = "START_DATA",
	  [4] = "END_DATA",
	  [5] = "START_STACK",
	  [6] = "START_BRK",
	  [7] = "BRK",
	  [8] = "ARG_START",
	  [9] = "ARG_END",
	  [10] = "ENV_START",
	  [11] = "ENV_END",
	  [12] = "AUXV",
	  [13] = "EXE_FILE",
	  [14] = "MAP",
	  [15] = "MAP_SIZE",
  };
