perf tools: Fix possible (unlikely) buffer overflow
cppcheck reported: [tools/perf/util/sysfs.c:50]: (error) Width 4096 given in format string (no. 1) is larger than destination buffer 'sysfs_mountpoint[4096]', use %4095s to prevent overflowing it -> All other places in the kernel that use STR(PATH_MAX) have a buffer size of PATH_MAX + 1.
