C{,XX}FLAGS: change -fdebug-prefix-map for cmake and meson Both of them build inside a builddir. This change ease the debugging process.

environment: set -ffile-prefix-map We're setting -fdebug-prefix-map to strip directory prefixes from debug info, which will help ccache and reproducibility. However, -fdebug-prefix-map doesn't help with those macros like __FILE__ and __BASE_FILE__, which needs another flags: -fmacro-prefix-map. Replaces -fdebug-prefix-map with -ffile-prefix-map which is an alias for both `-fdebug-prefix-map` and `-fmacro-prefix-map`. (This flag is available since GCC 8 and Clang 10)
