rtla/timerlat: Fix "Previous IRQ" auto analysis' line
The "Previous IRQ interference" line is misaligned and without
a \n, breaking the tool's output:
## CPU 12 hit stop tracing, analyzing it ##
Previous IRQ interference: up to 2.22 us IRQ handler delay: 18.06 us (0.00 %)
IRQ latency: 18.52 us
Timerlat IRQ duration: 4.41 us (0.00 %)
Blocking thread: 216.93 us (0.03 %)
Fix the output:
## CPU 7 hit stop tracing, analyzing it ##
Previous IRQ interference: up to 8.93 us
IRQ handler delay: 0.98 us (0.00 %)
IRQ latency: 2.95 us
Timerlat IRQ duration: 11.26 us (0.03 %)
