Spaces in Generalized Time/UTC Time

[Hallvard B Furuseth <h.b.furuseth@usit.uio.no>]

slapd/schema_init.c:check_time_syntax() accepts initial and trailing
spaces in Generalized Time and UTC Time.  I'd like to remove that,
since it is countrary to draft-ietf-ldapbis-syntaxes-06.txt.

Also, I'll remove the tests for whether the berval with the time
is \0-terminated; these tests look redundant.

(I'm updating the code to accept the full time syntaxes in
draft-ietf-ldapbis-syntaxes-06.txt.)
