man/man2const/TIOCLINUX.2const: Document CAP_SYS_ADMIN requirement for TIOCL_SETSEL modes

CAP_SYS_ADMIN was previously required for the entire TIOCL_SETSEL
subcode, but is now only needed for a subset of the selection modes,
since linux.git 2f83e38a095f (2025-01-13; "tty: Permit some
TIOCL_SETSEL modes without CAP_SYS_ADMIN").

The CAP_SYS_ADMIN requirement for TIOCL_SELMOUSEREPORT was further
corrected in linux.git ee6a44da3c87 (2025-04-11; "tty: Require
CAP_SYS_ADMIN for all usages of TIOCL_SELMOUSEREPORT").

Admittedly, there are kernels where CAP_SYS_ADMIN was briefly not
required for TIOCL_SELMOUSEREPORT, even after Linux v6.7, but this was
a mistake which is now fixed in all up-to-date stable kernels.
Therefore, we still document CAP_SYS_ADMIN as required "since Linux
6.7" in this case.
