crypto: tcrypt - Drop leading newlines from prints

The top level print banners have a leading newline. It's not entirely
clear why this exists, but it makes it harder to parse tcrypt test output
using a script. Drop said newlines.

tcrypt output before this patch:

[...]
      testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes)

tcrypt output with this patch:

[...] testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes)
