uhd: replace file_string() with string() for deprecation reasons

Patch from moritz.fischer@student.kit.edu

[1] http://www.boost.org/doc/libs/1_46_1/libs/filesystem/v3/doc/deprecated.html
[2] http://www.boost.org/doc/libs/1_46_1/libs/filesystem/v3/doc/index.htm

Boost 1.36 appears to have string(), so this should be safe to use.
