[PATCH V2] remote-helpers/test-bzr.sh: do not use grep \s

Using grep "devel\s\+3:" to find at least one whitespace
is not portable on all grep versions:
Not all grep versions understand "\s" as a "whitespace".

The + as a qualifier for "one or more" is not a basic regular expression:
use egrep instead of grep.
Use a literal TAB followed by SPACE like this [	 ] instead,
which is more portable than [:space:]
