enrich versioning with build deps

[alessio]

The version command now displays the list of
build dependencies.

Also fix version's command output stream.

version's output should go to stdout as it's the command's
objective to actually display versioning information.

A practical example follows.

This is the information presently displayed by appd version --long:

alessio@phoenix:~/work/cosmos-sdk$ build/simd version --long
name: sim
server_name: simd
version: goz-phase-1-866-g70fa17b55
commit: 70fa17b55a97e99f2db09a9769416cf52a962193
build_tags: netgo,ledger
go: go version go1.15.2 linux/amd64

The following is appd version --long's new output:

alessio@phoenix:~/work/cosmos-sdk$ build/simd version --long
name: sim
server_name: simd
version: goz-phase-1-870-gcc5473e0b
commit: cc5473e0b49f18f2b728f1b6eea43aab3ed80e3b

[tac0turtle]

LGTM.

[amaury1093]

lgtm.

Would like to understand the context of this addition: did a user ask for it? In what use-cases is it useful (one could just go to github to check the same thing)?

[alessio]

@amaurymartiny yep: #7835

Plus I bet users would find extremely useful while debugging to know what version of the cosmos-sdk their app builds on.

[alexanderbez]

ACK (so long as this is only visible with the --long flag).
