[PATCH] Small fix to HP timing printing

[Chung-Lin Tang]

Hi, when developing my dynamic linker DSO sorting patch [1], and measuring its
cycle performance, I found a small error in the HP_TIMING_PRINT trailing zero
setting; the '\0' should be set at MIN(Len,string length), instead of always
at the 'Len' position. Encountered some weirdness in printing counter results
because of this.

Okay for master?
