Linux 5.0 compat: Use totalram_pages()

(This is the ported SPL part of this patch)

totalram_pages() was converted to an atomic variable in 5.0:

https://patchwork.kernel.org/patch/10652795/

Its value should now be read though the totalram_pages() helper
function.

deadlock between mm_sem and tx assign in zfs_write() and page fault

(This is the ported SPL portion of this patch)

The bug time sequence:
1. thread #1, `zfs_write` assign a txg "n".
2. In a same process, thread #2, mmap page fault (which means the
`mm_sem` is hold) occurred, `zfs_dirty_inode` open a txg failed,
and wait previous txg "n" completed.
3. thread #1 call `uiomove` to write, however page fault is occurred
in `uiomove`, which means it need `mm_sem`, but `mm_sem` is hold by
thread #2, so it stuck and can't complete, then txg "n" will
not complete.

So thread #1 and thread #2 are deadlocked.

Add BuildRequires gcc, make, elfutils-libelf-devel

This adds a BuildRequires for gcc, make, and elfutils-libelf-devel
into our spec files. gcc has been a packaging requirement for
awhile now:

https://fedoraproject.org/wiki/Packaging:C_and_C%2B%2B

These additional BuildRequires allow us to mock build in
Fedora 29.

(This is the backported SPL equivalent of the original ZFS patch)
