Namhyung Kim f787d9519f perf tools: Fix strbuf_addf() when the buffer needs to grow
This was found during chasing down the header output regression.  The
strbuf_addf() was checking buffer length with a result of vscnprintf()
which cannot be greater than that of strbuf_avail().

Since numa topology and pmu mapping info in header were converted to use
strbuf, it sometimes caused uninteresting behaviors with the broken
strbuf.

Fix it by using vsnprintf() which returns desired output string length
regardless of the available buffer size and grow the buffer if needed.
