Optimize dependency management by reducing header inclusions. This
reduces hidden dependencies, improves modularity, and enhances
compilation performance.

The default sysfs path is always set to '/sys' unless the SYSFS_ROOT
environment variable is defined.
To address security concerns, secure_getenv() is used within
util_path_sysfs() to protect against malicious values in SYSFS_ROOT.
Additionally, constructing the sysfs path dynamically in an allocated
buffer, rather than using a fixed-size buffer, helps prevent potential
buffer overflows.
These modifications also significantly improve testability by allowing
sysfs read and write operations to be redirected to an alternative file
path, which enables testing without affecting the active system state.

The function is no longer required since the removal of the PHYSDEVPATH
entry in /sys/block/%s/uevent with commit 39aba963d937 ("driver core:
remove CONFIG_SYSFS_DEPRECATED_V2 but keep it for block devices") in
2010.

Under QEMU user can attach disk with smth like:
```
-device virtio-scsi-ccw,... -device scsi-hd,...
```
So virtio block device appears as '/dev/sda' instead of '/dev/vda'.
chreipl assumes all '/dev/sd*' disks as FCP disks, which is not a
case in such setup.
