    build: Remove local copy of ax_code_coverage.m4
    
    Since we now depend on other macros from autoconf-archive, remove the
    local copy of this one. When building from git, autoconf-archive will
    need to be available. When building from a tarball, the macros will have
    been copied into the tarball during dist, so autoconf-archive is
    unnecessary. When building from git via JHBuild, m4-common (a wrapper
    for autoconf-archive) is used automatically.
