[PATCH] lib: fwts-battery: use PRIu32 format specifier, fixes cppcheck warning

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Use the correct format specifier for a uint32_t, fixes cppcheck warning:

[src/lib/src/fwts_battery.c:423]: (warning) %d in format string (no. 1)
requires 'int' but the argument type is 'unsigned int'.
