util.c: make "Out of memory" messages a bit more informative

Since these are emitted in multiple places and are not expected during
any normal operation, it makes sense to report the caller name.

* util.c (print_quoted_string_ex, print_quoted_string_ex, dumpiov_upto,
dumpstr): Replace error_msg with error_func_msg.
