This patch is the result of

  git-grep -l 'error_report.*strerror' | xargs perl -p -i~ ../t

with ../t containing

  s{error_report\("(.*): \%s"(, .*)?, 
strerror\((.*)\)\)\;}{error_report_errnoval\($3, "$1"$2)\;}

Like the previous patch to use error_report_errno, this patch does not
contain any cleanups of the occasional idiosyncratic messages.  That
is left to the future.

No functional change, since error_report_errnoval does exactly what
this previous open-coded pattern does.
