Remove build rule for ld.config.28.txt prebuilt

Generated with `python gen_buildfiles.py 28` after applying
the corresponding change to
development/vndk/snapshot/gen_buildfiles.py.

Starting from the P VNDK snapshot, the linker config file will be
built and installed from the source tree at the time the VNDK
snapshot is installed to the system.img (of Q+), rather than
installing the prebuilt from /prebuilts/vndk/v{VER}. The installed
linker config file is used for both system and vendor processes,
thus should be built from the most up-to-date ld.config.txt
template in the source tree of the system partition.

Test: m -j vndk_v28_arm64; check /system/etc/ld.config.28.txt
