[PATCH 19.07] scripts: getver.sh: Fix version when running on local 19.07 branch

[Baptiste Jonglez]

From: Baptiste Jonglez <git at bitsofnetworks.org>

When building from a local branch based off the "openwrt-19.07" branch,
version computation is wrong, for instance:

    r10194+1004-c53f62b111

The number of local commits (1004 in this case) is wrong because it is
computed against master.  As a result, it wrongly counts *all* commits
since the beginning of the openwrt-19.07 branch as local commits.

The fix is to compare to the openwrt-19.07 branch instead, which gives the
expected result such as:

    r11192+6-8b0278a17e
