Make /emul/ writable to provide possibility of unforcing ASan related options.

Some packages fail to build with ASan because we force -fno-common compiler
switch in ASan builds. Athough the right thing to do would be fixing failed
packages itselves, sometimes it's not possible due to, say, difficult
package structure.

asan-force-options now makes /emul/ writable to provide possibility of
unforcing ASan related options. That would allow us to run gcc-unforce-options
right in package's spec file and re-force ASan related options without
-fno-common switch.
