misc/cgo/testshared: increase size limit in size check

Recently in Fedora we switched binutils ld's separate-code on. This
led to increased size of binaries, especially on 64k aligned arches.
For example trivial test binary size grew from 80k to 211k on ppc64le
tripping the size check(RHBZ#2030308). Therefore adjusting the size limit.
