[PATCH] fuzz: fix unbound variable in build.sh

[Alexander Bulekov]

/src/build.sh: line 76: GITLAB_CI: unbound variable
Fix that.

This change is in preparation to revert:
7602748c ("qemu: manually build glib (#5919)") on OSS-Fuzz.
Reverting as-is produces an unbound variable complaint when we try to
build the fuzzers in the OSS-Fuzz container.
