g10/sign: sign_file: use iobuf_read for higher detached signing speed
* g10/sign.c (sign_file): Use iobuf_read instead of iobuf_get for
reading data from detached file.
--
This patch reduces iobuf_read per byte processing overhead and speeds
up detached signing.
Detached signing speed on AMD Ryzen 5800X (4.3GiB file, SHA256):
gpg process
user time
before: 3.951s
after: 1.898s (2.0x faster)
