[pgpool-committers: 10009] pgpool: Use psprintf() instead of snprintf().

[Tatsuo Ishii]

Use psprintf() instead of snprintf().

Previously fixed size buffers were used for snprintf in the file. It's
not appropriate to use snprintf here because the result string could
exceed the buffer size and it could lead to incomplete command or path
used after.

Backpatch-through: 4.1.
