From commit 9df1c28bb752 ("bpf: add writable context for raw tracepoints"),
a new type of BPF_PROG, RAW_TRACEPOINT_WRITABLE has been added.

Since this BPF_PROG_TYPE_RAW_TRACEPOINT_WRITABLE is not listed at
bpftool's header, it causes a segfault when executing 'bpftool feature'.

This commit adds BPF_PROG_TYPE_RAW_TRACEPOINT_WRITABLE entry to
prog_type_name enum, and will eventually fixes the segfault issue.
