build: return ability to build without OpenSSL linking

[oleg-jukovec]

We already had the ability to build tt without linking with OpenSSL and with CGO_ENABLED=0:

tt/magefile.go

Line 67 in 648f98a

BuildTypeNoCgo BuildType = "no"

But it was broken with the go-tarantool/v2 by directly usage of the go-tlsdialer. We could return the ability to build without OpenSSL with a build tag inside tt (and optional usage of the go-tlsdialer). See go-tarantool/v1 as an example:
