FLUSH LOGS should ignore SET GLOBAL READ_ONLY.

The log tables are by nature PERFORMANCE_SCHEMA tables,
which should not be affected by SET GLOBAL READ_ONLY or FLUSH TABLES

The implementation of FLUSH TABLES WITH READ LOCK already ignored log tables.
Now with this patch, the implementation of LOCK TABLE also ignore a
global read lock for log tables, which was the missing symmetry.

In many cases, binaries can no longer dump core after calling setuid().

Where the PR_SET_DUMPABLE macro is set, use the prctl() system call 
to tell the kernel that it's allowed to dump the core of the server.
