test/bpf: Fix compilation with V=0

When the quiet mode was enabled, the $(CLANG) var would previously have
a '@' at the start, which caused errors while attempting to make in this
directory because it would be run in the context of a shell rather than
directly as a make instruction. Move the $(QUIET) to the start of
individual make instructions to resolve this compilation failure.
