configs/lego_ev3_defconfig: bump Linux to 4.19.315 to fix compilation error
The Linux kernel failed to build since commit e88225ed882 (package/binutils:
make 2.41 the default version). The new version contains the commit
790756c7e0229 ("ARM: 8933/1: replace Sun/Solaris style flag on section
directive") that fixes the issue.
