Subject[PATCH 8/9] perf tools: Align buildid list output for short build ids
Date
With shorter md5 build ids we need to align their
paths properly with other build ids:

$ perf buildid-list
17f4e448cc746582ea1881528deb549f7fdb3fd5 [kernel.kallsyms]
a50e350e97c43b4708d09bcd85ebfff7 .../tools/perf/buildid-ex-md5
1805c738c8f3ec0f47b7ea09080c28f34d18a82b /usr/lib64/ld-2.31.so
