Remove the dead mobbase base-skill path

static_npc_mobbase_stats.baseSkills never matches a static_skill_skillsbase
token on dev (2007496699 on 2208 rows is no known skill hash and is absent
from the client), so applyMobbaseSkill never added a skill and only cost a
skillsbase query per mob spawn. No value changes. Nothing reads the
baseSkills/skillAmount columns now; the table goes in 3.6.
