Fix BUFFER_OVERFLOW.SPRINTF in zos-remote-plugin.c

Replace sprintf with snprintf to prevent potential buffer overflow
when formatting logString buffer.

Svace report:
  Warning: An element of array '&logString[0]' of size 200 is accessed
  by an index with values in [0, +inf] which may lead to a buffer overflow.
  Format string: 'Linux (%s): type: %s'. Filled values can have unlimited
  string length. (CWE120, CWE121, CWE122, CWE124, CWE134, CWE20)
