s390/boot: fix compiler error due to missing awk strtonum
The strtonum awk function is a GNU extension and is not available with
all versions of awk. The link of bzImage fails with this error message:
>> awk: line 2: function or never defined
>> awk: line 2: function strtonum never defined
objcopy: --pad-to: bad number: arch/s390/boot/compressed/vmlinux
Drop the awk script and the --pad-to objcopy parameter it generated and
use a FILL pattern with an appropriate alignment in the linker script
for the arch/s390/boot/compressed/vmlinux file.
Fixes: f6780686525c ("s390/boot: pad bzImage to 4K")
