freeswitch-stable: fix gcc8 warnings

Add two patches that were submitted upstream to address warnings that
occur when using gcc 8.3 (like arc does currently) which turn into
errors (-Werror).

+    FS-11783: [core] quiet gcc truncation warning
+    
+    With -Wstringop-truncation gcc warns about calls to bounded string
+    manipulation function "strncpy" that may either truncate the copied
+    string or leave the destination unchanged. To avoid the warning when the
+    result is not expected to be NUL-terminated, it is suggested to call
+    "memcpy" instead.

+    FS-11783: [mod_say_ja] quiet overflow warning
+    
+    With -Wformat-overflow gcc warns about calls to formatted input/output
+    function "sprintf" that might overflow the destination buffer.
+    
+    In this case gcc does not know the upper bound of tm_min and assumes
+    that up to 11 bytes might be written to buffer (3 bytes). But we know
+    that tm_min can only be within the range 0 to 59.
