linux/linux.mk: fix commit d06dca38bb0373a13736a349f7795713458a2188 - remove extra bracket

Commit d06dca38bb0373a13736a349f7795713458a2188 (linux: cleanup
kconfig fixup processing) moved the initramfs setup out of an
enclosing statement but kept the closing bracket.

Remove the extra bracket to fix a syntax error in sed processing.

Fixes:
  >>> linux 6.4-rc1 Updating kernel config with fixups
  /bin/bash: -c: line 1: syntax error near unexpected token `)'
  /bin/bash: -c: line 1: `/usr/bin/sed -i -e '/^\(# \)\?CONFIG_INITRAMFS_ROOT_GID\>/d' /home/data/buildroot.experimental/build/linux-6.4-rc1//.config && echo 'CONFIG_INITRAMFS_ROOT_GID=0' >> /home/data/buildroot.experimental/build/linux-6.4-rc1//.config)'
