cmd/compile/internal/ssa: TestNexting/dlv-dbg-hist failing on linux-386-longtest builder because it tries to use an older version of dlv which only supports linux/amd64 [1.13 backport]

[gopherbot]

@dmitshur requested issue #39309 to be considered for backport to the next 1.13 minor release.

@gopherbot Please consider for backport, this is a test skip for a test that is expected not to pass due to insufficient environment preconditions. This is to uncover additional test failures on the linux-386-longtest builder that would otherwise be masked.

Change https://golang.org/cl/237617 mentions this issue: [release-branch.go1.13] cmd/compile/internal/ssa: skip TestNexting with old Delve on linux/386

Approving for backport. This test could be masking other issues.
