bootperf: Fix bootperf to run again

I was getting this error:

  >>> "server/site_tests/platform_BootPerfServer/control" is an ambiguous pattern.
  Disambiguate by passing one of these patterns instead:
     ^server/site_tests/platform_BootPerfServer/control$
     ^server/site_tests/platform_BootPerfServer/control.perfalerts$

...so I have done so.

BUG=None
TEST=Ran:
  ../platform/crostestutils/bootperf-bin/bootperf --output_dir \
    ~/bootperf das1 2
