ExecContext: Fix output handling

This PR fixes miscellaneous issues with handling the output of a command run via ExecContext, most of them directly or indirectly introduced by commit 6db73873e7.

lib.Result.repr() Fix missing f-qualifier

repr() tries to format a variable in an f-string without "f". Fix that.

lib.Result.repr(): Fix binary stdout exception

repr() tries to decode binary stdout as string and fails without a backup. Fix that.

lib.ExecContext|.Distro: Ignore stdout_str newline

Ignore newline at the end of Result.stdout_str if only one line of output is wanted from an executed shell command. The output of both uname and mktemp are used wrongly in that regard.

lib.ExecContext._put(): Clean up temporary file

_put() can leave temporary files behind if one of its shell commands fails, fix that.

lib.ExecContext._put(): Fix forgotten input

_put() doesn't put: An empty stdin is passed to tee, a regression introduced with 6db73873e7, fix that.
