tools: Fixed MIPS builds due to struct flock re-definition

Building perf for MIPS failed after 9f79b8b72339 ("uapi: simplify
__ARCH_FLOCK{,64}_PAD a little") with the following error:

note: originally defined here

This is due to the local copy under
tools/include/uapi/asm-generic/fcntl.h including the toolchain's kernel
headers which already define 'struct flock' and define
HAVE_ARCH_STRUCT_FLOCK to future inclusions make a decision as to
whether re-defining 'struct flock' is appropriate or not.

Make sure what do not re-define 'struct flock'
when HAVE_ARCH_STRUCT_FLOCK is already defined.
