env: avoid possible NULL pointer access
env_attr_lookup call env_attr_walk with
callback = regex_callback.
In env_attr_walk
attributes = strchr(entry_cpy, ENV_ATTR_SEP)
will return NULL if ENV_ATTR_SEP is not found.
In the aftermath regex_callback may call
strlen(attributes)
with a NULL value which will lead to a failure.
The problem was indicated by scan-clam.
