Optimize binary size of syscall tables

The syscall tables were implemented as an array of const char*
strings. Each of them required a relocation entry of 8 bytes each,
wasting both binary size and dirty memory at load time.
This CL stores the syscall table as a single string (per table)
separating each syscall with a \0, and an array of offsets into that
string.

On the standalone arm64 release build this saves
File size:
  -65KB (before:1,034,864 after:969,328)
ELF sections:
 .rela.dyn         before:0x022d58  after:0x016f38 = -48K
 .rodata           before:0x00e34f  after:0x00f36f = +4KB
 .data.rel.ro      before:0x015bf8  after:0x011c98 = -16KB
