MFC r367302:

sysvshm: pass relevant uap members as arguments

Alter shmget_allocate_segment and shmget_existing to take the values
they want from struct shmget_args rather than passing the struct
around.  In general, uap structures should only be the interface to
sys_<foo> functions.

This makes one small functional change and records the allocated space
rather than the requested space.  If this turns out to be a problem
(e.g. if software tries to find undersized segments by exact size
rather than using keys), we can correct that easily.
