[PATCH 2/2] strbuf.h: use BUG(...) not die("BUG: ...")

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

In 7141efab248 (strbuf: clarify assertion in strbuf_setlen(),
2011-04-27) this 'die("BUG: "' invocation was added with the rationale
that strbuf.c had existing users doing the same, but those users were
later changed to use BUG() in 033abf97fcb (Replace all die("BUG: ...")
calls by BUG() ones, 2018-05-02). Let's do the same here.
