perf llvm-utils: Remove bashism from kernel include fetch script
Like system(), popen() calls /bin/sh, which may/may not be bash.
Script when run on dash and encounters the line, yields:
exit: Illegal number: -1
checkbashisms report on script content:
possible bashism (exit|return with negative status code):
exit -1
Remove the bashism and use the more portable non-zero failure
status code 1.
