e2fsprogs: simplify handling of ldconfig for target variant

e2fsprogs now has a proper autoconf check for ldconfig, so we can
simply pass the apropriate ac_cv_path_LDCONFIG variable at configure
time, and it gets used at build/install time without having to force
LDCONFIG=true at every step.

Since the E2FSPROGS_INSTALL_TARGET_OPTS become the default, we can get
rid of them entirely.
