Avoid printing NUL characters in 'message' (bug#75900)

* src/xdisp.c (vmessage): Increase buffer size to fit an extra
multibyte character.  On buffer overflow, drop the last multibyte
character to determine an accurate byte length.

(cherry picked from commit 8812f526cfb145e00ee4cb74eac05b25953da02c)
