[Tile-serving] [osm2pgsql] change directory for tests if TEST_DATA_DIR is present (#496)

This patch solves the problem of missing files in tests.
To run tests from any directory one need to add environment variable
```
export TEST_DATA_DIR=/path/to/osm2pgsql_sources
```
(if the variable is not present, the tests will get data from current directory)

ctest did not need it, it had WORKING_DIRECTORY in it.
If we want to just run executable without setting TEST_DATA_DIR, only auto-hardcoding in source can help. Will do it if really needed.
