perf tests bpf: Remove unused ptrace.h include from LLVM test

The bpf-script-test-kbuild.c script, used in one of the LLVM subtests,
includes ptrace.h unnecessarily, and that ends up making it include a
header that uses asm(_ASM_SP), a feature that is not supported by clang
<= 4.0, breaking that 'perf test' entry.

This ended up leading to the ca26cffa4e4a ("x86/asm: Allow again using
asm.h when building for the 'bpf' clang target"), adding an ifndef
__BPF__ to the arch/x86/include/asm/asm.h file.

Newer clang versions accept that asm(_ASM_SP) construct, so just remove
the ptrace.h include, which paves the way for reverting ca26cffa4e4a
("x86/asm: Allow again using asm.h when building for the 'bpf' clang
