MultiBaseLocalDiskRepositoryManagerTest: fix for running on Mac from Eclipse

The alternateRepositoryLocation test was failing when running from
Eclipse on Mac because the created repository location would be:

  /private/var/rest/of/path

while the alternateBasePath is:

  /var/rest/of/path

This difference comes from the fact that on Mac the /var is a symlink to
/private/var and the creation of the repository would resolve the
location using getCanonicalFile().

Use alternateBasePath.toRealPath() to resolve any symlinks in the
alternateBasePath.

NOTE: this issue doesn't show up when running tests from bazel as
bazel's sandboxing uses different path locations.
