recipes-devtools/llvm/llvm_%.bbappend: fix the build of bpftrace ptest failed

Due to commit [1][2], llvm-native was added to bpftrace to provide llvm-objcopy
for the ptest.

But because of commit [3], llvm-native requires opengl in DISTRO_FEATURES
to support libllvm.

In order to make the build of bpftrace ptest work, explicitly add libllvm to
PACKAGECONFIG for llvm-native if ptest enabled.

According to [2][3], bpftrace used llvm-objcopy to generate BTF data for unit tests,
regardless opengl in DISTRO_FEATURES, enable accelerated software renderer or not
does not have side effect on bpftrace
