perf hists: Fix up srcline histogram key formatting

Problem introduced in:

  commit 5b5916696051 "perf report: Honor column width setting"

Where the left justification signal was after the width, which ended up,
when the width was, say, 11, always printing:

	%11.11-s

Instead of src:line left justified and limited to 11 chars.

Resulting in a like:

    70.93%  %11.11-s  [.] f2                     tcall

When it should instead be:

    70.93%  tcall.c:5    [.] f2                     tcall
