rtla: Fix consistency in getopt_long for timerlat_hist

[ Upstream commit cfb1ea216c1656a4112becbc4bf757891933b902 ]

Commit e9a4062e1527 ("rtla: Add --trace-buffer-size option") adds a new
long option to rtla utilities, but among all affected files,
timerlat_hist misses a trailing `:` in the corresponding short option
inside the getopt string (e.g. `\3:`). This patch propagates the `:`.

Although this change is not functionally required, it improves
consistency and slightly reduces the likelihood a future change would
introduce a problem.
