configure: Fix parsing of compiler version
Avoids grabbing warnings on invocation of the target compiler, e.g.
#define VLC_COMPILER "clang: warning: argument unused during compilation: '-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.4.sdk' [-Wunused-command-line-argument]"
vs. after fix:
#define VLC_COMPILER "Apple clang version 17.0.0 (clang-1700.0.13.3)"
