Bug#475168: Bug #475168 is still present in libgcrypt11 1.4.5-2

[sacrificial-spam-address at horizon.com]

certtool still makes 25 120-byte reads from /dev/urandom, fetching 3000
bytes (14400 bits) when 32 (256 bits) is more than enough.

To quote "man 4 random":

	"if any program reads  more than 256 bits (32 bytes) from the
	kernel random pool per invocation, or per reasonable reseed
	interval (not less than one minute), that should be taken as a
	sign that its cryptography is not skilfully implemented."
