Log message:
intel-backlight: don't set SETUID_ROOT_PERMS when UNPRIVILEGED

Requested by nia@.
In unprivileged installations the binary becomes setuid to the
unprivileged user so it doesn't work even when ran as root via sudo,
due to privilege dropping upon execution.

XXX: Arguably this fix is wrong. It doesn't make sense to me that pkgsrc
infrastructure uses mode 4511 in SETUID_ROOT_PERMS when UNPRIVILEGED.

Log message:
intel-backlight: Use SETUID_ROOT_PERMS so normal user can set backlight

This is the recommended way to install the program and is also the default
behaviour in FreeBSD ports. Bump PKGREVISION.

Log message:
sysutils: Add intel-backlight

This package contains the intel_backlight program from intel-gpu-tools,
which allows controlling the backlight level on certain Intel(R) GPUs,
including i915.

Since it performs direct PCI access, it must be run as root.
