Fix stack buffer overflow in `rvermicelliDoubleExecReal()` (#392)

Fix stack buffer overflow in rvermicelliDoubleExecReal

Remove unconditional snprintf that writes input buffer length into
fixed 255-byte stack buffer. On inputs >255 bytes, this causes stack
smash detected by FORTIFY_SOURCE. The removed lines were debug
scaffolding that duplicated the DEBUG_PRINTF above them.

Fixes crash on patterns like ".*literal" with buffers >255 bytes.
