[Buildroot] [V2 1/2] sngrep: fix dependency error.

[Adam Duskett <aduskett@gmail.com>]

sngrep will complain if libgcrypt isn't compiled. I am not sure
how or why I didn't notice this issue to begin with, but
I added it as a dependency and select it in the Config.in file now.
I also added 'depends on BR2_PACKAGE_LIBGPG_ERROR_ARCH_SUPPORTS' as per
baruch's suggestion.
