lib/test_bpf.c: don't use gcc union shortcut 

Older gcc's (mine is gcc-4.4.4) make a mess of this.

lib/test_bpf.c:74: error: unknown field 'insns' specified in initializer
lib/test_bpf.c:75: warning: missing braces around initializer
lib/test_bpf.c:75: warning: (near initialization for 'tests[0].<anonymous>.insns[0]')
lib/test_bpf.c:76: error: extra brace group at end of initializer
lib/test_bpf.c:76: error: (near initialization for 'tests[0].<anonymous>')
lib/test_bpf.c:76: warning: excess elements in union initializer
lib/test_bpf.c:76: warning: (near initialization for 'tests[0].<anonymous>')
lib/test_bpf.c:77: error: extra brace group at end of initializer
