Subject: [PATCH] sh: remove CONFIG_VSYSCALL reference from UAPI

The definition of AT_SYSINFO_EHDR was gated between CONFIG_VSYSCALL to
avoid a default gate VMA to be created. However that default gate VMA
was removed entirely in commit a6c19dfe3994
("arm64,ia64,ppc,s390,sh,tile,um,x86,mm: remove default gate area").

Remove the now unnecessary conditional.
