### Contribution description

This PR cleans up the bmp180 driver test application:
- it removes an unnecessary dependency to printf_float: there is no use of float formatter in calls to printf
- it fixes how negative temperature are displayed

<!--
Put here the description of your contribution:
- describe which part(s) of RIOT is (are) involved
- if it's a bug fix, describe the bug that it solves and how it is solved
- you can also give more information to reviewers about how to test your changes
-->

### Testing procedure

- Verify the removal of printf_float decreases significantly the ROM size
- Verify negative temperatures are correctly displayed (might be difficult now) or otherwise compare to the hts221 driver application which uses the same logic

<!--
Details steps to test your contribution:
- which test/example to compile for which board and is there a 'test' command
- how to know that it was not working/available in master
- the expected success test output
-->
