travis: remove -Werror

Using -Werror in CFLAGS make ./configure to fails with:
 checking whether the C compiler works... no
 configure: error: in `/home/travis/build/LudovicRousseau/libusb':
 configure: error: C compiler cannot create executables
 See `config.log' for more details

-Werror had no effect because CFLAGS was _not_ exported.
