Remove pieces of the vDSO's fake section table mechanism that were left behind when the vDSO build process reverted to using "objdump -S" to strip the userspace image.
One of the removed pieces is a 0x340 byte reservation (for 64-bit) in the .rodata section. Trimming that fat drops the current image's size to under 4k, i.e. reduces the effective size of the userspace vDSO mapping by a full page.
