* Update go to 1.15 to reduce binary size
Go made improvements to reduce binary size, cf https://golang.org/doc/go1.15
> Go 1.15 reduces typical binary sizes by around 5% compared to Go 1.14 by eliminating certain types of GC metadata and more aggressively eliminating unused type metadata.
In my test, this equates to about 3 mb diff between Go 1.13 and Go 1.15:

-rwxr-xr-x 1 root root 33M Aug 31 14:44 piper-go-115
