selftests/bpf: Fix compilation error in get_uprobe_offset()

In get_uprobe_offset(), the call to procmap_query() use the constant
PROCMAP_QUERY_VMA_EXECUTABLE, even if PROCMAP_QUERY is not defined.

Define PROCMAP_QUERY_VMA_EXECUTABLE when PROCMAP_QUERY isn't.

Fixes: 4e9e076 ("selftests/bpf: make use of PROCMAP_QUERY ioctl if available")
