Remove redundant _alpm_strtrim() in be_local.c 

When reading the "desc" file in _alpm_local_db_read(), some
strings are trimmed and checked for length > 0 before their
use/duplication subsequently. They are then trimmed again
when there is no need to.

The following code snippet should illustrate it clearly:

while(fgets(line, sizeof(line), fp) &&
	strlen(_alpm_strtrim(line))) {

	char *linedup;
	STRDUP(linedup, _alpm_strtrim(line), goto error);
	info->groups = alpm_list_add(info->groups, linedup);
}

This patch removes the redundant _alpm_strtrim() calls in
_alpm_local_db_read() such as the one inside the STRDUP shown
above.
