Resolves: 158342

Summary: db backend path handling could be impoved to deal with "//", "..", etc.
Changes:
util.c:
modified rel2abspath so that if the given path contains "//", calls the
normalize function, and the normalize function eliminates the repeated
separators.
ldbm_config.c, ldbm_instance_config.c:
before setting the nsslapd-directory paths, pass them to rel2abspath to clean
up the paths.
