mock: use MRAA_PIN_NAME_SIZE for strncpy to avoid truncation

This fixes the following compilation warnings:

mraa/src/src/mock/mock_board.c: In function ‘mraa_mock_board’:
mraa/src/src/mock/mock_board.c:156:5: warning: ‘strncpy’ output truncated before terminating nul copying 8 bytes from a string of the same length [-Wstringop-truncation]
