minor gc-libgcrypt.c fix

[Simon Josefsson]

Applied.

FYI, secure memory requires setuid, something most applications aren't
or shouldn't be.

        * lib/gc-libgcrypt.c (gc_init): Disable secure memory by default.
        Applications that requires it should initialize libgcrypt
        manually.
