The relevant failures are:

--- FAIL: TestCloneNEWUSERAndRemapNoRootDisableSetgroups (0.00s)
        exec_linux_test.go:74: Cmd failed with err fork/exec /usr/bin/whoami:
in
valid argument, output: 
--- FAIL: TestCloneNEWUSERAndRemapNoRootSetgroupsEnableSetgroups (0.00s)
        exec_linux_test.go:114: Unprivileged gid_map rewriting with
GidMappingsE
nableSetgroups must fail
--- FAIL: TestEmptyCredGroupsDisableSetgroups (0.00s)
        exec_linux_test.go:122: fork/exec /usr/bin/whoami: invalid argument

This means that your system doesn't support some kinds of user namespace
features.  The test should arrange to not fail when those features are not
supported.
