Ian Rogers bac74dcbd4 perf tools: Switch printf("...%s", strerror(errno)) to printf("...%m")
strerror() has thread safety issues, strerror_r() requires stack
allocated buffers.

Code in perf has already been using the "%m" formatting flag that is a
widely support glibc extension to print the current errno's description.

Expand the usage of this formatting flag and remove usage of
strerror()/strerror_r().
