Update fsck_minix.c

[HackingRepo]

This PR fixes a potential vulnerability in util-linux/fsck_minix.c where the return value of sprintf() is not checked. sprintf() may return a negative value on failure, which could be misused in pointer arithmetic or array indexing, leading to memory safety issues.

• Replaced sprintf() with snprintf() for prevent buffer overflow

• Added checks for return value and buffer limits

• risk Level Low — fix is non-breaking and adds sanity checks.

• Identified using Snyk

• CWE-120: Buffer Copy without Checking Size of Input

• High Confidence (Score 801)
