perf: Robustify proc and debugfs file recording
While attempting to create a timechart of boot up I found perf didn't
tolerate modules being loaded/unloaded. This patch fixes this by
reading the file once and then writing the size read at the correct
point in the file. It also simplifies the code somewhat.
