build: fix permission errors with ld.sh

[jengelh]

• First, make install with DESTDIR runs into a permission error with:

  • export DESTDIR=/home/abuild/rpmbuild/BUILDROOT/cuarzo-srm-0.3.2.1-0.x86_64
  • /usr/bin/meson install -C x86_64-suse-linux --no-rebuild /home/abuild/rpmbuild/BUILD/SRM-0.3.2-1/src/../scripts/ld.sh: line 7: /etc/ld.so.conf.d/srm.conf: Permission denied

• Second, ldconfig is in sbin, and sbin is not traditionally in PATH.

  /home/abuild/rpmbuild/BUILD/SRM-0.3.2-1/src/../scripts/ld.sh: line 8: ldconfig: command not found

  (If sbin is in PATH, that is because Debian has a non-standard /etc/login.defs)

• Third, ldconfig itself runs into a permission error.

  /sbin/ldconfig: Can't create temporary cache file /etc/ld.so.cache.qf9tee: Permission denied

I think ld.sh should just be removed.

Hi, yes, it seems that with pkg-config, it is no longer required. Thanks!
