[committed][nvptx, testsuite] Fix typo in gcc.target/nvptx/march.c

[Tom de Vries via Gcc-patches]

Hi,

The dg-options line in gcc.target/nvptx/march.c:
...
/* { dg-options "-march=sm_30"} */
...
currently doesn't have any effect because it's missing a space between '"' and
'}'.

Fix this by adding the missing space.

Tested on nvptx.

Committed to trunk.

Thanks,
- Tom
