skein-infra: Simplify logging of mount actions

Both bind_* functions remove the SKEIN_CGIT_ROOT prefix from its log
messages in an effort to remove redundant information. With commit
efdbb04 ("skein-infra: Rename instances/ to home/") however, it is no
longer clear from the path alone that a path under SKEIN_CGIT_ROOT is
being operated upon. Use the full path in the log message to resolve
this.

The logging aliases ladd() and ldel() are only used in the respective
bind_mount() and bind_umount() functions and we don't expect this to
change any time soon. Rename log() to log_mount() and call the latter
directly from within both bind_* functions to improve clarity.
