bp_create_unique_id modified to return positive id

[Issue]    http://suprem.sec.samsung.net/jira/browse/TWF-1521
[Problem]  bp_create_unique_id sometimes returned negative
           integer because int value overflowed and became negative
[Solution] added mask for generating high number to prevent it from
           becoming too large
[Verify]   Run browser, run command
           "dlogutil TAB_ADAPTOR BROWSER_PROVIDER" in shell
           check if there is any DISK_BUSY message while adding tabs,
           you should add at least 30 tabs.
