perf: make sure that the tools/include/uapi/asm-generic directory exists

* before trying to copy unistd.h into it

* older kernels don't have uapi in tools/include and do_configure fails
  with:
  DEBUG: Executing shell function do_configure
  cp: cannot create regular file '.../perf/1.0-r9/perf-1.0/tools/include/uapi/asm-generic/unistd.h':
  No such file or directory
  WARNING: exit code 1 from a shell command.

* tools/include/uapi was added in kernel 4.8 with
  https://github.com/torvalds/linux/commit/c4b6014e8bb0c8d47fe5c71ebc604f31091e5d3f
  tools: Add copy of perf_event.h to tools/include/linux/
