systemd-boot: Remove -mfpmath=sse option from cflags

EFI sources in systemd uses -mgeneral-regs-only which conflicts
with -mfpmath=sse specified by OE via tune arguments. It needs to
be removed, clang errors about it and fails the build

Fixes
error: the 'sse' unit is not supported with this instruction set
