linux-libc-headers: Fix build failure with fixed input and output files instead of pipe

This is an amendment for
2322dc4 "linux-libc-headers: Fix build failure by using fixed temporary file instead of pipe"
which moves just the temporary input file from /tmp to build directory. But the
build directory may not in the same file system with the output file,
/dev/null, either and thus make it possible to trigger that bug, 67f846b, in
binutil v2.31.

This patch puts both the input and output files into build directory for good.
