Fix CVE-2022-46285: Infinite loop on unclosed comments

When reading XPM images from a file with libXpm 3.5.14 or older, if a
comment in the file is not closed (i.e. a C-style comment starts with
"/*" and is missing the closing "*/"), the ParseComment() function will
loop forever calling getc() to try to read the rest of the comment,
failing to notice that it has returned EOF, which may cause a denial of
service to the calling program.
