[PATCH v2 4/4] x86/vdso: Rename "required_syms" to "requested_syms"

[Sean Christopherson]

The "required" moniker implies that vdso2c will fail if one of the
defined symbols is not found, which is simply not true, e.g.
VDSO32_NOTE_MASK is quite obviously 32-bit only and not required
for the 64-bit image.
