perf script: Improve srcline display for BTS
Change the order of the output to put the srcline last.
It puts the branch 'from address' and 'to address' on the same line,
which is how it would be without the source line reference.
So it makes it consistent and much easier to read.
E.g. old format:
4028fc main+0x2c (/bin/ls)
/build/buildd/coreutils-8.20/src/ls.c:1269 => 40d8a0 set_program_name+0x0 (/bin/ls)
new format:
4028fc main+0x2c (/bin/ls) => 40d8a0 set_program_name+0x0 (/bin/ls)
/build/buildd/coreutils-8.20/src/ls.c:1269
