enable __FILE__ trim

[xufang-lisa]

Description

It's better to use relative path instead of full path while debugging and macro FILE is used.
If the full path is needed, the option "TBB_FILE_TRIM" can help.
for example:
When debugging an application by gdb, if the stack shows the full path like this, it seems inappropriate.

It's better to show the relative path like this.

Would be good to attach some output examples (from asserts, GDB).
