syslog: Fix heap buffer overflow in __vsyslog_internal (CVE-2023-6246)
__vsyslog_internal did not handle a case where printing a SYSLOG_HEADER
containing a long program name failed to update the required buffer
size, leading to the allocation and overflow of a too-small buffer on
the heap. This commit fixes that. It also adds a new regression test
that uses glibc.malloc.check.
