lineage: soong: replace space with colon on TARGET_LD_SHIM_LIBS

that way we can split the shim list logically into multiple lines like

TARGET_LD_SHIM_LIBS := /system/bin/gpsd|/vendor/lib/libshim_gpsd.so \
    /system/lib/libexynoscamera.so|/vendor/lib/libexynoscamera_shim.so \
    /system/lib/libstagefright.so|/system/lib/libstagefright_shim.so

to not have one single huge line
