[glib/wip/pwithnall/meson-cleanups: 2/3] build: Use cc.check_header() to check malloc.h

[Philip Withnall <pwithnall src gnome org>]

commit a14553a5701cf87eaf67db38975d5ad3481268c4

    build: Use cc.check_header() to check malloc.h
    
    Since Meson 0.47, this can be used to check a header with compilation,
    rather than just stat. This removes a workaround.
