htsopt: fold HTS_TRAVEL_TEST_ALL into the hts_travel_scope enum

The -t "test all" flag was a stray #define sitting next to the scope
enum; make it an enum constant so the named travel values live in one
place. The mask (HTS_TRAVEL_SCOPE_MASK) stays a #define: it selects the
scope out of opt->travel, it is not a member of the value set.

Name and value (1 << 8) are unchanged, so every use site compiles
identically and opt->travel stays plain int. No ABI change.
