fio: Remove --disable-static from EXTRA_OECONF

As of commit OE-Core:773c9e18071d71454473dd81aff911104a2e9bc6
EXTRA_OECONF is appended with the option --disable-static on
DISABLE_STATIC variable and this cause the error:

    DEBUG: Python function sysroot_cleansstate finished

    Bad option --disable-static

    --disable-numa         Disable libnuma even if found
    --enable-libhdfs       Enable hdfs support

So, we need to disable this option.
