[pushed: r16-5207] EXPERIMENTAL_SARIF_SOCKET: decode errno when reporting errors [PR115970]

[David Malcolm]

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to trunk as r16-5207-ge7e1f2e40a2d1c.

gcc/ChangeLog:
        PR diagnostics/115970
        * diagnostics/sarif-sink.cc (maybe_open_sarif_sink_for_socket):
        Add "%m" to error messages, so that we print the string form of
        errno.
