    shell: Remove last reference to "INCLUDES"
    
    c61d9e5a95d replaced use of INCLUDES with AM_CPPFLAGS, but there was
    still one reference to INCLUDES in shell/Makefile.am.
    AM_CPPFLAGS will apply globally, so we don't need to explicitly set
    per-target CFLAGS/CPPFLAGS to its value.
