scripts: Fix possible cause of cros_generate_breakpad_symbols crash

Browse Source 
Use the ":" builtin command to prevent the increment of $ERROR_COUNT from
ever failing under strict mode (i.e. "set -e").
cros_generate_breakpad_symbols failed for some reason, and this is my best
guess as to the cause.  That is, the post-increment would otherwise fail
when $ERROR_COUNT is zero because it would have a non-zero exit status.

TEST=Manually ran script
