vmlinuz-boot.bin: remove unnecessary '-nostartfiles' and '-nodefaultlibs' linker flags

The vmlinuz-boot.bin is linked using the vmlinuz-boot.ld linked scripts so
the flags - '-nostartfiles' and '-nodefaultlibs' are unnecessary.
Worse they are incorrect and start triggering link errors with the version of
ld.bfd on Ubuntu 21.04.

This patch removes these linker flags.
