Fix crash in LZMA module when the Sandbox is enabled.

Browse Source 
This patch fixes a crash in our LZMA module where liblzma will allocate
slightly more data than it is allowed to by its limit, which leads to a
crash.

o Major bugfixes (compression):
- Fix crash in LZMA module, when the Sandbox is enabled, where
liblzma would allocate more than 16 MB of memory. We solve this
by bumping the mprotect() limit in the Sandbox module from 16 MB
to 20 MB. Fixes bug 22751; bugfix on 0.3.1.1-alpha.
