MAINTAINERS: remove unneeded file entry in INPUT section

Commit b9401c658d2c ("MAINTAINERS: add gameport.h, serio.h and uinput.h to
INPUT section") adds further header files in ./include/linux/ and
./include/uapi/linux to the INPUT section, but the file
./include/linux/uinput.h does not exist since commit a11bc476b987 ("Input:
uinput - fold header into the driver proper") removed this header file
in 2017.

Fortunately, ./scripts/get_maintainer.pl --self-test=patterns complains
about a broken reference. Remove the file entry referring to the
non-existing header file in the INPUT section.
