[CRIU] Compile error: expected string literal before ‘)’ token

[Huang Qiang]

I am trying to compile a recent CRIU git snapshot (8a7dc1d) and ran
into this error:

restorer.c: In function ‘__export_restore_task’:
restorer.c:699: error: expected string literal before ‘)’ token

I need to delete the third colon and the compile passed, I'm not quiet
familiar with gcc inline assembly, maybe it's related to the gcc version.

My gcc version is 4.3.4, maybe you guys can take a look at this.
