fix(lib/gnss/test): mark buildRawFrame noinline to avoid GCC false positive (#26877)

Browse Source 
GCC 14.3.0 emits `-Wstringop-overflow` when `RtcmTest::buildRawFrame()`
is optimized and inlined.

This change marks the helper `noinline` to keep it out of that optimization path.

Preserves the existing logic and only changes how the compiler emits the test helper.

Fixes https://github.com/PX4/PX4-Autopilot/issues/26875
