termux-tools: Unset LD_LIBRARY_PATH in wrappers

Previously the wrappers assumed that if
	/system/bin/linker64
that LD_LIBRARY_PATH should be set to /system/lib64. This seems
to not always be the case (see #192) and hopefully the system
binaries should work without LD_LIBRARY_PATH being set, so we
just unset it before calling the system binary.
