[PATCH 2/5] KernelShark: Fix compilation issues on Fedora 32

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

From: Tzvetomir (VMware)  Stoyanov <tz.stoyanov@gmail.com>

Included <string.h> to fix this compilation error:
   "error: ‘string’ in namespace ‘std’ does not name a type"
Converted fontHeight and stringWidth to inline to fix these
compilation errors:
   "multiple definition of `fontHeight';"
   "multiple definition of `stringWidth';"

Signed-off-by: Tzvetomir (VMware)  Stoyanov <tz.stoyanov@gmail.com>
